MapIterator

opApply wrapper to work around the problem that it isn't possible to have a static array opApply() argument because 'ref' is not allowed with a static array. Instead, the wrapper slices the argument and passes the slice to the 'foreach' body.

If the value type is 'void', the iteration delegate will only have a key argument.

Functions

iterate int iterate(Dg dg, Element element): Invokes dg with the key and, unless V is 'void', the value of element.
iterate int iterate(Dgi dg, size_t i, Element element): Same method as above, but with counter
