import std.conv, std.stdio;

void main(){
    /// int
    static assert(to!string(15, 10) == "15");  // success
    // assert(to!string(15, 10) == "15");  // failure
    assert(to!wstring(15, 10) == "15"w);  // success
    assert(to!dstring(15, 10) == "15"d);  // success
    writeln(to!string(15, 10));  // ??

    /// uint
    static assert(to!string(15u, 10) == "15");  // success
    // assert(to!string(15u, 10) == "15");  // failure
    assert(to!wstring(15u, 10) == "15"w);  // success
    assert(to!dstring(15u, 10) == "15"d);  // success
    writeln(to!string(15u, 10));  // ??

    /// long
    static assert(to!string(15L, 10) == "15");  // success
    assert(to!string(15L, 10) == "15");  // success
}


In the case of "(r)dmd foo.d", only to!string(int, radix) and
to!string(uint, radix) return "0" at run time with any radix
though "15" is returned when compiled with "-debug".

Environment: DMD 2.064.2 on Win7 SP1 32-bit
