C API's often use a opaque struct pointer as a handle. Mapping such a
struct to D using a forward declaration, I noticed that UFCS doesn't work:
struct State;

State* s = new_state();
foo(s); // ok
s.foo(); // compile error
Error detail:
Error: struct State is forward referenced when looking for 'foo'
Error: struct State is forward referenced when looking for 'opDot'
Error: struct State is forward referenced when looking for 'opDispatch'
I'm wondering if anything would be harmed by removing this restriction.
As a workaround I can use "struct State {}", but that feels wrong.
This is a compiler bug. You can report it here: http://d.puremagic.com/issues/
