ok. fine. no unnecessary, hidden allocations then.

// ------------------

module test;

import core.stdc.stdio : putchar;

nothrow @nogc void main()
{
     string str = "abc;def;ab";

     ulong len = str.length;

     for (ulong i = 0; i < len; i++)
     {
         if (cast(int) str[i] != ';')
             putchar(cast(int) str[i]);
     }
}
