Occasionally I've noticed myself some inconsistencies wrt to compiler
warnings between meson & make .
But cirrus seems generally happy now
https://cirrus-ci.com/build/4964687915253760

To recap so far;

- I like your changes and renames on the parser/lexer; it indeed looks much
cleaner now and will help with future improvements.
- I also like the addition of executeStringInternalMethod ; it'll help us
add more stuff in the future (reminder that for the original patch I
implemented the methods I'd like more, but string operations are quite
more).

- AFAICT no test cases / results have changed with your versions; is this
correct ?
