[parenscript-devel] Feature proposal: Optimize away constant arithmetic

[Vladimir Sedach]

This is a feature I'm planning to add to ParenScript that involves
eager evaluation for arithmetic constants, so for example:

(js (+ foo.bar 0)) => "foo.bar;"
(js (+ foo.bar 1 -1)) => "foo.bar;"
(js (+ foo.bar 2 3)) => "foo.bar + 5;"

This would make the generated Javascript be a few bytes shorter, but
more importantly it seems that many Javascript implementations don't
do constant arithmetic optimizations themselves, so it would speed up
the generated Javascript as well.
