Yeah, but what if you've misspelled a name? Shouldn't it be easy to fix those kinds of mistakes? That's why I'd recommend formatting like...
my @folk = ();
...etc. Of course that's also problematic if you want to edit an individual letter. So I find the style below a bit better (especially when using a modern editor like edlin). Plus it uses a more descriptive name than the bland "@folk"...
