Hi,
The snippet below will produce an "infinite loop" because 
obviously "ubyte u" will overflow after 255:

import std.stdio;
void main(){
    ubyte u = 250;
    for(;u<256;++u){
        writeln(u);
    }
}

Question: Is there a way (Flag) to prevent this?

Matheus.

What do you want to do? If you just want to count to 255 then use 
a foreach


If you want to prevent overflow you must either use BigInt or 
wrap ubyte in a struct that doesn't allow overflow
