Some iterable in builtins
XXX: For JS backend: Currently due to Nim's inner buys, using of some iterable functions in this modules may result in Error: ...:
- list(...)
- filter/map/... as func (using iterator is okey) (solved after Nim-2.1.1)
For details, trace:
- closure iterator: https://github.com/nim-lang/Nim/issues/4695 (solved after Nim-2.1.1)
- concept about for loop: https://github.com/nim-lang/Nim/issues/9550#issuecomment-2045173674
