toChars Bug?

[Bottled Gin]

Greetings

This small code snippet works:

//
import std.conv;
import std.stdio;

void main() {
   writeln(toChars!10(45));
}


But if I change toChars!10 with toChars!2, I get:

/tmp/test.d(6): Error: template std.conv.toChars cannot deduce 
function from argument types !(2)(int), candidates are:
[snip]std/conv.d(6020):        std.conv.toChars(ubyte radix = 10, 
Char = char, LetterCase letterCase = LetterCase.lower, T)(T 
value) if ((radix == 2 || radix == 8 || radix == 10 || radix == 
16) && (is(Unqual!T == uint) || is(Unqual!T == ulong) || radix == 
10 && (is(Unqual!T == int) || is(Unqual!T == long))))

toChars!8 and toChars!16 do not work either.
