The problem is that the function needs to return
int, but given two uints, their difference may be
greater than int.max, so simply subtracting them
will not work. So the best I can come up with is:
Should of course be:
int compare2(uint x, int y)
{
return (x > int.max) ? 1 : (cast(int)x - y);
}
i have the ints 4, 7, 0 and 1 how can i Concatenate them into
four thousand seven hundred and one.

If we talking at compile time definition:
int myint = 4_7_0_1;
Would work.
However I'll assume its at runtime you really want this.
I.e. convertin
Rikki Cattermole:
int myint = to!int("4" ~ "7" ~ "0" ~ "1");
And to concatenate them there is "join" (joiner is not yet usable
here, because to!() doesn't yet accept a lazy input,
unfortunately).
Now they are not strings, and the positions of 10^ doesn't
change then:
int myint = (1000

So at all the implementation will look something like this:
int opCmp(T, U)(const(T) a, const(U) b) @primitive
if(isIntegral!T && isIntegral!U)
{
alias CommonType!(Signed!T, Signed!U) C;
static if(isSigned!T && isUnsigned!U)
{
return (b > cast(Unsigned!C)C.max) ? -1 : cast(C)a -

Remember that enums have copy-paste semantics. So, this is the
