[Issue 9279] New: Static array return value implicitly converted to immutable dynamic array
http://d.puremagic.com/issues/show_bug.cgi?id=9279

          Summary: Static array return value implicitly converted to
                   immutable dynamic array
          Product: D
          Version: D2
         Platform: All
       OS/Version: All
           Status: NEW
         Severity: major
         Priority: P2
        Component: DMD
       AssignedTo: nobody@puremagic.com

The following compiles without error:

---
char[2] b()()
{
   char[2] ret;
   return ret;
}

string a()
{
   return b();
}
---

Changing b to a normal function causes the correct error message that an
implicit conversion of char[2u] to string is not possible.

Note that this affects std.digest.digest.toHexString(). Returnung
toHexString(digest) from a function will result in a corrupted string.
