At least a year ago `const`/`immutable` `std.typecons.Tuple`-s with classes
worked as associative array keys. The fact it fails at runtime now is rather
nasty. It should either work or fail to compile.
---
import std.typecons;
void main()
{
alias T = Tuple!Object;
int[const T] aa; // No CT errors
aa[T()] = 1;
aa[T()] = 1; // Error at runtime
}
---
object.Error: TypeInfo.compare is not implemented
---
E.g. fixing Issue 11590 will fix this issue by rejecting such associative
arrays to compile unless Issue 1824 is fixed.
