I think std.typecons.Tuple should sopport a immutable item too, if possible:


import std.typecons: Tuple;
alias immutable(char)[5] Foo;
Tuple!(Foo) bar() {
    Foo f;
    return Tuple!(Foo)(f);
}
void main() {}


DMD 2.058 Head:

...\dmd2\src\phobos\std\typecons.d(383): Error: slice this._field_field_0[] is
not mutable
test.d(5): Error: template instance
std.typecons.Tuple!(immutable(char[5u])).Tuple.__ctor!(immutable(char[5u]))
error instantiating
