--------------------------------
struct S {}
int foo(alias A)(S s) { return 1; }
int baderror = S().foo!(X);
--------------------------------


Error is:
bug.d(3): Error: no property 'foo' for type 'S'


Ideally would be:
bug.d(3): Error: undefined identifier X.


This can be quite problematic in large UFCS chain expressions, like what you get when using ranges. A small typo can take quite a while to track down with the current diagnostics.

I think this is already fixed in the latest beta, it gives:

temp.d(3): Error: undefined identifier X, did you mean struct S?

Yes it's a dup of some recently fixed bug, can't remember the ID though.
