Mixed int/BigInt foreach interval

[bearophile]

It seems my original post of this thread was confused and not clear enough. In that post I have also mixed two different things (a Phobos enhancement request that doesn't require a lot of discussion, and a more complex discussion about usefulness of possible D language changes. See below).

Multi-precision integers are important. In several languages they are even built-in (like in Lisp/Scheme languages, Haskell, Python, some modern variants of Forth, and so on).

I didn't ask to turn BigInts into D built-ins. What I was asking is if there are generic ideas worth changing in D language to allow a better creation and integration of library-defined multi-precision integers :-) (example: ideas like opCast(bool) are not specific to BigInts, but they allow to implement better BigInts).
Maybe there are no ways to improve the situation.
