Using an int iterator creates an error

[VirtuGuy]

Int iterators don't work in the latest experimental commit, which at the time of reporting is c58f169.

This is being caused by Dead Code Elimination (DCE), one of the ways hscript validates an iterator is by checking if the hasNext and next functions exist, and in your case Haxe is inlining and optimizing them out.
Maybe we should also specifically check for IntIterator to avoid this, but the iterator is probably not gonna work either way if the functions for it are missing.
