Still not fixed in D2.052 :)

-------------------------------------
void explode(string foo)() {
  int gremlins = 0;
  string bar = foo[gremlins .. $];
}

void main(){ explode!("BOOM")(); }
-------------------------------------

'_D1x27__T7explodeVAyaa4_424f4f4dZ7explodeFZv8__dollark' means 'void

Reduced test case for 1.068:

-----------------------------------
void main(){
    const string s = "BOOM";
    int gremlins = 0;
    string bar = s[gremlins .. $];
}
-----------------------------------
Undefined symbols:
  "_D1y4mainFZv8__dollark", referenced from:
      _D1y4mainFZv8__dollark$non_lazy_ptr in y.o
     (maybe you meant: _D1y4mainFZv8__dollark$non_lazy_ptr)
ld: symbol(s) not found
collect2: ld returned 1 exit status
--- errorlevel 1
-----------------------------------

The equivalent for 2.054:

-----------------------------------
void main(){
    enum string s = "BOOM";
    int gremlins = 0;
    string bar = s[gremlins .. $];
}
-----------------------------------
