           Summary: Opaque struct parameter type should not be allowed
           Product: D
           Version: D2
          Platform: All
        OS/Version: All
            Status: NEW
          Keywords: accepts-invalid
          Severity: major
          Priority: P2
         Component: DMD

struct Opaque;

Opaque ret_func();  // ok: error

void void_func(Opaque);  // no error!
-----

$ dmd test.d
test.d(3): Error: cannot return opaque struct Opaque by value

The void_func is not triggering errors, but it should.

There are various other cases not caught yet, even for return types which are
partially checked now. Examples:

-----
struct S;

S ret_f1();     // ok: fails
S[] ret_f2();   // should fail
S[1] ret_f4();  // should fail
S[]* ret_f3();  // should fail

void call_f1(S);     // should fail
void call_f1(S[]);   // should fail
void call_f1(S[1]);  // should fail
void call_f1(S[]*);  // should fail

void main() { }

I would point out that references to opaque structs should compile.

In your examples:

S[]
S[]*

Should compile, even if S is opaque, as these are just references to S.

Yeah, my mistake.
