I think readf("%s") reads everything available. readf(" %s\n") might help but personally, I say avoid readf. Just use readln and to!int instead auto line = readln(); if(line.length == 0) writeln("please enter a number"); age = to!int(line); to is from import std.conv

In general, of course, this is a bad idea - there's probably a reason that destructor does the thing it's doing. If you're sure skipping it is what you want, go ahead. @Biotronic, the code you have provided may be exactly what I am looking for. Let me explain my situation. I have a library

In your case, the postblit of Bar is still going to run and add a ref to it's count when you place it in Foo, right? That means that if you don't destroy it, it will leak memory or resources. Actually no. Since when Foo (class that instantiates Bar) gets GCed, that is the point that I need
