Call/cc is a way of applying the argument function to the current
continuation.  As such, it seems (as with #value:) that #callCC would
be a method sent to the block.

  BlockClosure>>callCC
    ^self value: thisContext continuation

Example usage:

  retryCount := [:cont | retry := [cont value: retryCount+1]. 0] callCC.
