As for const / immutable, I guess I don't see this as such an issue because
I've been dealing with it in C++ for so long. You either have to commit 100%
to using const attributes or not use them at all. Anything in between is
fraught with problems.
Well, the problem is essentially that you can have a function like:
void foo(int i) { ... }
... and if you pass it an immutable or const int, this is not a problem, because
you're passing by value.
But now try
void foo(BigInt i) { ... }
... and it won't work when passed a const/immutable variable, even though again
you're passing by value. That's not nice, not intuitive, and generally speaking
makes working with complex data types annoying.
It's why, for example, std.math.abs currently works with BigInt but not with
const or immutable BigInt -- which is very irritating indeed.
