Description Tomas Lindquist Olsen 2008-10-06 07:44:22 UTC 
I wasn't actually aware this was valid in D:

module test;
struct foobar;
foobar* foo() {
  return null;
}

I thought structs needed a body, I can't find anywhere this is documented as valid, did I miss it?. Also how is this supposed to play with eg. TypeInfo ? The error messages reported by DMD when trying different stuff with one aren't very descriptive.

GtkD makes use of this for representing opaque (to GtkD at least) C struct types. They are never defined.
Comment 2 Walter Bright 2012-01-22 16:41:05 UTC 
This is now documented.
