Why does this template not have the desired result?

The problem with that though is that with size arguments >
int.max will wrap when being cast to int (T)? i.e.:
import std.stdio;
template inBounds(T, T size)
{
enum result = (size >= T.min && size <= T.max);
}
void main(string[] args)
{
writefln("%s", inBounds!(int, int.max + 1).result); //true,
wrong!
}
