Hi all,

I was looking at the implementation of some of the flow control methods and I have a question with the method whileTrue.

First of all, I can see two identical implementation in the classes BlockClosure and BlockContext the implementation is this

whileTrue: aBlock
    "Ordinarily compiled in-line, and therefore not overridable.
    This is in case the message is sent to other than a literal block.
    Evaluate the argument, aBlock, as long as the value of the receiver is true."

    ^ [self value] whileTrue: [aBlock value]

I'm assuming here that there's another class Block I'm missing (something like the literal block mentioned in the comment) which is the one that contains the logic I was looking for. But I'm not able to find any other whileTrue method in my image. What's the difference between BlockClosure and BlockContext?

Thanks,
Erlis
