What is interesting is to be able to reimplement #ifTrue:ifFalse: and co in any object in the system and to use it.

Now in practice it is difficult performance wise.

As an experiment we overrided mustBeBooleanIn: so #ifTrue:ifFalse: and co would work on any object. However this hack is slow and interesting only for experiments IMO.

I asked in the bug report to add a setting... But no one answered and it was integrated. Marcus said we'll add a setting later.

Ok thanks.
I do not see why this is interesting to have that.

Because someone activated the method "mustBeBooleanMagicIn:" by default whereas it was just a hack to experiment.

Basically you have an optimized message sent to a non boolean. For over a week now, in this case the code is executed as a DoIt with a non optimized message instead of raising the mustBeBoolean error.

Hi guys

Does anybody have an idea why when I open a transcript and recompile a method I get

UndefinedObject>>ExecuteUnOptimizedIn: (model is Undeclared)
