Re^2: RFC: Simulating Ruby's "yield" and "blocks" in Perlby LanX (Canon)

Thanks a lot, not yet.
But is this Ruby feature really demonstrating coroutines?
We don't have multiple entry points and there's no reentering at the last suspended exit point.
Are you maybe confusing Python's yield with Ruby's yield?

I really should start reading Knuth ...
FWIW I demonstrated at YAPC:EU 2011 how to emulate Perl6's gather/take in Perl5.

Well, I think a convincing prototype which fits well into the language is the first step for implementation.
And backwards compability is always an issue, most module authors wouldn't chose a feature which is only available in the very newest release.
One of our perlmongers just told us at the last meeting that at work he's stuck with 5.8.6 on AIX!
