{
	void foo() {}
}

struct S
{
	alias t = T!();
	alias t this;
}

void main()
{
	S s;
	s.foo();
}

Still there in DMD master. The error message is:

xx.d(15): Error: expression has no value
Comment 2 RazvanN 2018-10-19 14:01:25 UTC 
This is a weird case. The alias is part of the struct, but the actual function is not. I would say that the correct behavior is the current one:

Error : no property foo for type S.

Note that writing s.t.foo works. In my opinion, this is the real bug.
