When I compile the HelloWorld.d demo code on version 3.4.1 in debug mode the resulting file size is 26.4MB, when I compile the same code with 3.5.0 the file size is 70.7MB, that is quite a jump in size. I am using DMD V2.072.2 on 64bit Debian testing.

As you are probably aware, GtkD auto-generates code. Unfortunately, adding the ability to remove event handlers generated an increase in the size of code, instead of just tracking the delegate directly it now uses a wrapper class to also track the connect flags and returned handlerId. Right now a unique wrapper class is generated for each event handler which I suspect is the primary culprit for the increase in size.

If this size increase is a major concern, one option might be for me to try to use a generic wrapper class instead of a generating a unique one. This would mean converting the generated code to cast the delegate before using it.

I'll let Mike chime in with his thoughts first though before looking too much into it.
