so i am very happy to see a high level language get that potential. besides go only common lisp has that ability that i am aware of. others are either to low level (rust/c/c++) or to obscure. not even java does it, although java is common enough that it still keeps distribution easy enough.
to me this means now is a good time to start using red because now i can be sure that i'll be able to build tools that can be shared easily so i won't just be limited to create toys for myself.
64bit is the next big thing on the roadmap. so no need to worry about that. it will happen.
