How do you reach the second 'Boo'? Iff -> does not create a Sub
but a Block instance then Luke's code can be interpreted as a
much smarter version of

   sub foo()
       enter: 42;
       if $?RETURN_LABEL { goto $?RETURN_LABEL }

    say "Boo!";
    say goto foo::enter; # goto sets up $?RETURN_LABEL
    say "after goto";

which of course prints

   after goto

The smartness is in the value that &prefix:{'->'} returns
while in the snippet above it is explicitly coded.

Or do I completely misunderstand the distinction between
blocks and closures?
