Audrey Tang 提到:
However, in S02 you removed the Code class and replaced it with Routine, but that does not really work; for example, a bare block is a Code, but it cannot be a Routine since it can't be wrapped in place, and caller() would bypass it when considering caller frames.
I should've been more explicit. While I don't really have a problem with replacing Code with Callable (except the latter is more wordy, so why not replace Callable with Code...), the issue is that your S02.pod edits indicates that a variable &foo must always be bound to a Routine object. However, variable with the "&" sigil can be bound to a Block as well, so replacing Code with Routine at line 1487 and 1512 doesn't quite work. :-)
