python: various simplifications Use raw or multiline string litterals to make some hard-coded strings more readable. Replace some lambda constructs with more idiomatic generator expressions, removing several temporary sequences (conversions, contatenations, slices, arguments). Replace definitions with assignments when possible. Replace most python2/3 wrappers with code compatible with both versions. Use a non-printable ASCII characters instead of Unicode characters (in order to avoid unicode in python2). core: Close file open by 'slurp' after reading. coll_Q: remove as obsolete. conj: do not preserve metadata. env: Replace find with an optional argument to get. Search in outer environments with a loop instead of a recursion. (python is not intended for large recursions). readline: Copy the example from the docs. Write the history once. mal_types: clone: copy.copy() everything except callables. functions: construct fn* functions in steps, where they are used (there was no encapsulation anyway) Derive List and Vector from tuple, which is more efficient than list for immutable structures. Remove the need for __getitem__ stuff. maps: provide an asPairs iterator. printer: Introduce a pr_list helper like many other implementations. steps: Remove obviously backported stuff from first steps. Port forward the limitation of the exception backtrace size from step5 to later steps, so that REGRESS=1 does not crash stepA tests. Fix the detection of special forms (strings were accepted as well as symbols). Let try* benefit from TCO.

All: split types into types, env, printer, core. - types: low-level mapping to the implementation language. - core: functions on types that are exposed directly to mal. - printer: implementation called by pr-str, str, prn, println. - env: the environment implementation - Also, unindent all TCO while loops so that the diff of step4 and step5 are minimized.

import mal_types as types
Test uncaught throw, catchless try* . Fix 46 impls. Fixes made to: ada, c, chuck, clojure, coffee, common-lisp, cpp, crystal, d, dart, elm, erlang, es6, factor, fsharp, gnu-smalltalk, groovy, guile, haxe, hy, js, livescript, matlab, miniMAL, nasm, nim, objc, objpascal, ocaml, perl, perl6, php, plsql, ps, python, r, rpython, ruby, scheme, swift3, tcl, ts, vb, vimscript, wasm, yorick. Catchless try* test is an optional test. Not all implementations support catchless try* but a number were fixed so they at least don't crash on catchless try*.

from mal_types import MalException, List, Vector
All: move some fns to core. Major cleanup. - Don't import/require core until step4. - Define cond/or macros from step8

python: various simplifications Use raw or multiline string litterals to make some hard-coded strings more readable. Replace some lambda constructs with more idiomatic generator expressions, removing several temporary sequences (conversions, contatenations, slices, arguments). Replace definitions with assignments when possible. Replace most python2/3 wrappers with code compatible with both versions. Use a non-printable ASCII characters instead of Unicode characters (in order to avoid unicode in python2). core: Close file open by 'slurp' after reading. coll_Q: remove as obsolete. conj: do not preserve metadata. env: Replace find with an optional argument to get. Search in outer environments with a loop instead of a recursion. (python is not intended for large recursions). readline: Copy the example from the docs. Write the history once. mal_types: clone: copy.copy() everything except callables. functions: construct fn* functions in steps, where they are used (there was no encapsulation anyway) Derive List and Vector from tuple, which is more efficient than list for immutable structures. Remove the need for __getitem__ stuff. maps: provide an asPairs iterator. printer: Introduce a pr_list helper like many other implementations. steps: Remove obviously backported stuff from first steps. Port forward the limitation of the exception backtrace size from step5 to later steps, so that REGRESS=1 does not crash stepA tests. Fix the detection of special forms (strings were accepted as well as symbols). Let try* benefit from TCO.

Change quasiquote algorithm - Add a `vec` built-in function in step7 so that `quasiquote` does not require `apply` from step9. - Introduce quasiquoteexpand special in order to help debugging step7. This may also prepare newcomers to understand step8. - Add soft tests. - Do not quote numbers, strings and so on. Should ideally have been in separate commits: - elisp: simplify and fix (keyword :k) - factor: fix copy/paste error in let*/step7, simplify eval-ast. - guile: improve list/vector types - haskell: revert evaluation during quasiquote - logo, make: cosmetic issues
