Retry does not work

ruby-talk

“resume” won’t work well unless both your code and the user code know
each other (the user code must care that raise might resume; your code
must know how to fix up the exception cause). In that case, I think
you can make “retry” work, otherwise you can’t make them work well
anyway.

that is a good point, but the alternative seems to be passing proc or passing self. self seems like over kill, but passing proc is messy. no win situation here? perhaps this suggests another facility like raise but that does not halt execution. rather it moves up the call chain looking for a handler, if it finds one it executes, if not forget it, and then resumes execution. better RCR?

thanks,

It’s called “coroutine”. If you are going to write new RCR, I
recommend you to google it first.
