Hi,

I'm not sure this is in bugzilla, I tried finding something mentioning it 
but coudn't.

Compiling the below code results in the dmd compiler printing:
struct_bad_error.d(8): Error: 'this' is only defined in non-static member 
functions, not inner

====================
struct S {
	S opCall() {S s; return s;}
}
void main() {
	S s;
	//s = S(); // decent error message: "struct_bad_error.d(6):
		// Error: need 'this' to access member opCall"
	void inner() {
		s = S();
	}
}
=====================

What to do? Also found that having an empty () after the struct name is not 
the best error message: "struct_bad_error.d(5): Error: struct 
struct_bad_error.S() is used as a type"

Surely it could tell me I need to put an Identifier in the ()

Perhaps you want a static opCall ?

S foo;
foo(); // calls opCall
S(); // calls static opCall
