Description Don 2012-01-23 02:16:23 UTC 
template Foo(X)
{
 alias int Foo;
}

int m;
alias Foo!(m) XXX;

bug.d(7): Error: template instance Foo!(m) does not match template declaration Foo(X)

It should say something like, "m is not a type".

When no constraint is present indeed this could be an additional error message.
There's an helper for that in the compiler.

When there's a constraint this possibly new message should not be added since there's work to format them prettier.
