Ok, well asAlien seems to be used as conversion methods to ensure a passed object is an alien. What would you like to do instead? I'll integrate the primitive Error code changes this week and do any clean up. If you would like to suggest which variable bindings can be deleted I'll correct that.

Currently, if you got a bug in morphic code, there's a big chance in complete loss the display and no way to see anything or debug it.

Re: [Pharo-project] HostWindows rewrite

I agree: it would be useful to control host windows in some way, whether as described below, or via Wx, etc. The native windows/controls have their uses, though they are not (IMHO) the panacea that many believe them to be.

Notwithstanding this, IMO a really good feature would be the ability to create and manage native views within windows, where e.g. a Morph could be 'backed' by a native view. This feature alone is enough to later allow native controls (such as WebKit) to mix with 'light' controls with correct z-ordering/clipping/event handling etc. Of course one could retrofit such a feature, but using native views from the start would encourage any Morphic mods (or other widget set) to use native views and hence be ready for better integration.

I breaks when you put a real selector corresponding > to a compiled method What I can tell from your debugger picture is that it searches for a selector in SymbolTest that does not exist. Probably what happens is that you remove a trait method in the class definition, then the browser updates, but still refers to that removed trait method which is actually not present anymore. So the browser model is not in sync with the system model in this case. But the strange thing is that the browser always asks the class organizer for the methods, so maybe it's the organizer that does not reflect the change to the class (yet). So I don't know whether the browser is to blame or not. What I did now is to check first whether the class indeed defines a particular method before accessing it. This should avoid the problem, but maybe the real problem lies somewhere else.
