ISLisp in JS/Go: Standards-compliant Lisp smaller than Common-Lisp.
Note that the on-line JavaScript version does not handle #x prefixes correctly.
Integers are also limited to 31 bit:
(expt 2 31) => -2147483648
in contradiction to https://islisp-dev.github.io/ISLispHyperDraft/islisp-v23.html#integer_class
