Consider the following sniplet:

----------------------------------------------------------
template E(){
    enum E=["123"][0][$-1];
}
pragma(msg, E!());

import std.stdio;
void main() {
    writeln(E!());
}
----------------------------------------------------------

Compiling with "dmd" (r287) gives:

----------------------------------------------------------
(["123"][0u])[__dollar - 1u]
Undefined symbols:
  "_D1a6__T1EZ8__dollark", referenced from:
      _D1a6__T1EZ8__dollark$non_lazy_ptr in a.o
     (maybe you meant: _D1a6__T1EZ8__dollark$non_lazy_ptr)
ld: symbol(s) not found
collect2: ld returned 1 exit status
--- errorlevel 1
----------------------------------------------------------

where the expected output from the compiler should be:

----------------------------------------------------------
'3'
----------------------------------------------------------

and links the binary successfully.
