IMO this is a design mistake - the special case is preferred over the
common case which goes against the D philosophy of making the common

All COM instances are known at _compile_time_ as they're all required to
inherit from a special IUnknown interface so the compiler _knows_ if
indeed an interface represents a COM instance or not. This can be used
to handle this special case differently.
Interface i = new Class();
Object o = i; // should work for regular interfaces
The compiler can issue a compile-time error if i is COM since this is
known at compile type.
Exactly, I couldn't agree more.
