What is the purpose of #haltIf: aBlock? Right now, you can pass any of the following to Object>>haltIf: - aBlock taking an optional argument which is automatically set to the receiver of #halt - aSelector which looks up the call chain and halts if present - aBoolean
So, whatever the condition is, it seems like you should be able to evaluate it in the calling context. When would you ever need to use a block? Can we eliminate the block behavior? Or, who has a great war story about blocks saving them from imminent doom... Thx. Sean
