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
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...
