perl is a yucky language full of hacks like this... one of the reasons
why I love it :)

So while perl's syntax sugar allows my hands to type a bit less, I'll
often find myself following a C style and doing

return
unless statement;

In general, I will continue to say the 'if' test should be completely
separately from the statement, no matter how short either are.

Unless you get more than one or two independent 'if' tests like that,
then all those braces for a one-line test eat up wasted screen real
estate, slowing down the person reading the code.

So, if you gave me the choice above, I would choose option C, neither :)
