I think this is unexpected for most of D users, but AFAIK, current compiler
implementation (and Walter) intents this behavior. So I honestly mark this as
'enhancement'.

Forum discussion:
http://forum.dlang.org/thread/klc5r7$3c4$1@digitalmars.com

This program:

import std.stdio;
void foo(bool b) { writeln("bool"); }
void foo(long l) { writeln("long"); }
void main()
{
    foo(0);
    foo(1);
    foo(2);
}

Prints:

bool
bool
long

Integer literal 0 and 1 prefer 'bool' version than 'long' version.
