There seems to be some general consensus that some people would like to be
able to short-circuit functions like grep. Do you see no need for the code
block equivalent of C<next>/C<last>/C<redo>?
sub mygrep (&@) { ... }
@results = mygrep { $_ == 1 } (1..1_000_000);
How would you do it with out exceptions?
People have been quick to shoot down the various proposals for a standard
mechanism to short-circuit built-in and user-defined subroutines. Is this
because it shouldn't be done... or do people just not like ideas being
proposed to do it?

P.S. I'm curious. is the C<return> control implemented as macro for throwing
an exception that is caught and handled by a subroutine? I.e., is there a
parallel between how C<next>/C<last>/C<redo> and C<return> are implemented?
