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)
