           Summary: Cannot retrieve the return type of an auto-return

          Keywords: rejects-valid
          Severity: normal

Test case:

------------------------------
struct X {
    auto x() {
        return 0;
    }
}
pragma(msg, typeof(X.init.x));
static assert(is(typeof(&X.init.x) == int delegate()));
------------------------------
()
x.d(7): Error: static assert  (is(typeof(__error) == int delegate())) is false
------------------------------

The expected output is 'int()' and the static assert should pass. The '__error' comes out because DMD thinks X.init.x is forward-referenced.




This also causes a ICE when using with std.traits.ReturnType:

------------------------------
struct X {
    auto x() {
        return 0;
    }
}
static if (is(typeof(X.init.x) R == return)) {}
------------------------------
Assertion failed: (type), function AliasDeclaration, file declaration.c, line
376.
Abort trap
------------------------------
