void explode(char[] foo)()
{
int gremlins;
char[] bar = foo[gremlins..$];
}
void main(){ explode!("BOOM"); }
The above program prints the following when compiled:
C:\dmd\bin\..\..\dm\bin\link.exe main,,,user32+kernel32/noi;

This was tested with DMD 1.020 on Windows XP.
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 x.explode!("BOOM").explode().uint __dollar'.
Reduced test case for 1.068:
-----------------------------------
void main(){
const string s = "BOOM";
int gremlins = 0;
string bar = s[gremlins .. $];
}
-----------------------------------

-----------------------------------
The equivalent for 2.054:
-----------------------------------
void main(){
enum string s = "BOOM";
int gremlins = 0;
string bar = s[gremlins .. $];
}
