I think someone mentioned my superstition:

return $value # the keyword is not necessary

Also, I use for for hashes and foreach for arrays. I have no idea why just a habit I picked up and can't shake. So:

foreach (@array)

and

for (keys %hash)

Always, always, always. I say I do it because it is explicit, but maybe I am afraid of demons. However, I am not as strong as you George. I will not give this one up. It is too scary, too nerve racking. I am just not as brave as you. May your light shine on us all and clear the way, but for now I need to coward in the corner :)
