Re^2: keywords versus variables

I think perhaps it's balanced against other issues, though, and shouldn't necessarily be a singular goal.

Oh, definitely. It's a bit of a silly "metric", of course. My point about the complex data structures was that, if you have to do

$blah->{something}->{and_deeper}->[12]
[download]

you'll be pretty bug prone and so you might consider refactoring into something like

$deeper->item(12)
[download]

...which is why I put method calls on one lower level of egregiousness :)

Good point. Even if you are doing the former on some level, hiding it behind the latter for most code should still help cut down on bugs. Doing the complex one in one place and the simple one in lots of other places could be quite a maintenance win.	[reply]
