[Help-smalltalk] MethodWrapper

[Gwenaël Casaccio]

Hi,

I've made (very) small patch for the VM to support methodWrapper.
MethodWrapper are objects used to add behavior before and after
the method evaluation.

This patch ensure that the vm doesn't cast the object to the class format and
thus having wrong ivar offset. It also avoids the method check.

It is useful for pre and post conditions, test coverage.

You could find the patch at
