This refactors to "non-magic"[1] Perl[2]:
return $rc if defined($rc = function());
Is there anyone on this list working on Perl6 continuations? Any comment on
the proposed return_if "flow control"? Is it more like an exception or more
like spaghetti?
Notes:
1. for the definition of "non-magic" that includes folks knowing that
assignment returns a value
2. something to consider for the folks who have to maintain the code when
you get hit by a bus (or another job offer)
