xslt:
- The reader was returning the an odd args error when a hash-map literal
was not closed. This was because the the parsing error happened and
then the odd args test happened after and overwrote the parsing error.
- Also, fix the read-string function so that if an error is set by the
reader, this is converted to a full error that bubbles up.
c:
- read_list errors were not being detected/propagated in read_hash_map
after calling read_list.
zig:
- reader errors were not being caught in the rep loop until step 8, so
those errors in step6 and step7 were causing the REPL to exit.
- Reorder README to have implementation list after "learning tool"
bullet.
- This also moves tests/ and libs/ into impls. It would be preferrable
to have these directories at the top level. However, this causes
difficulties with the wasm implementations which need pre-open
directories and have trouble with paths starting with "../../". So
in lieu of that, symlink those directories to the top-level.
- Move the run_argv_test.sh script into the tests directory for
general hygiene.
