What do you do at the end of a sub?
"I am a sub";
I hate that. Nothing particularly wrong with it, it's valid perl, except that I hate it. The following is more to my liking
return "No! *I* am a sub.";
Hashkeys are a little more forgiving, because how often are you really going to have s p a c e s =>in between, or some such nonsense like others have pointed out, but as with my example above, I'll take being explicit
any time over being implicit
. I also like to do the following (mainly for visual effect):
$fooBar->Fooz( 'abc' => 1,
'aa0ec' => 221,
'abae' => 12,
'aecadf' => 145,
,)->pack( 'ab' => 11,
'cd' => 22,
