- Move apply logic in swap! to APPLY function in types and use that
for macroexpand
- Abort def! if error before updating the environment
- let* wasn't properly saving A2% for the final eval. Also, the
environment release check should be against the top-level EVAL env,
not the root repl env.
- (concat (list) ...) was broken so fix it to ignore empty lists that
aren't in the trailing position.
- nil, false and true in the reader were always being returned as
references (with an ref cnt) but we have the assumption that
references (14) are not ref cnt'd and are always part of a compound
type so fix the reader to just return the interned addresses.
Also:
- Add some step1 and step3 tests that were discovered during Basic
development.
- Move PR_MEMORY* to debug.in.bas
- Simplify Makefile deps
- Fix freeing in steps4-7 when error at deeper level
i.e. (prn (abc))
- add SLICE function to support concat implementation.
- tests/*: marked with deferable and optional runtest flags. Some
moving around of tests within different sections to more closely
align with the guide.
- runtest.py has --deferable/--no-deferable and
--optional/--no-optional to control whether tests marked as
deferable and optional are tested.
- Makefile: DEFERABLE and OPTIONAL top level flags to be passed to
runtest when running tests.
- Also, fix problems in java quoting revealed by step7 test changes.
- Some additioanl tests.
- Split step9 tests into optional but self-hosting requirements
(metadata on functions) and other optional (conj, metadata on
collections).
