[FWP] Fun with =>

[Sean McAfee <mcafee@umich.edu>]

This is a pretty trivial bit of fun, but I don't believe I've ever seen a
construct like this anywhere before.  From some code I'm working on to
parse RFC822 addresses:

----------------------------------------------------------------------
use strict;

sub enum {
    eval "sub $_[$_] () { $_ }" or die for 0 .. $#_;
}

BEGIN {
    enum SPECIAL => ATOM => COMMENT => QUOTED => DOMAIN =>
}
----------------------------------------------------------------------

(The fun I'm referring to is using => between several adjacent barewords,
and after the final one.)
