int main(string[] argv)
{

        size_t[string] bary;

        try{
                for(size_t i=0;i<(size_t.max -1);i++)
                {
                        bary["Key:" ~  to!(string)(i)] = i;
                }
        }catch(Exception e)
        {
                writeln(e);
        }
    return 0;
}
// This code will overflow?


bary.length <> size_t.max ?

32bit bary.length == 64bit bary.length ?
