I find the second way totally unreadable. I can't see the left side and right side at the same time. I read code like I read sentences, not like a table. I won't line up this paragraph with all the subjects on the left, verbs in their own column, and predicates justified to the right. The gap between the "my $foo" and the RHS is bigger than the left hand side! That makes me think of the break as a significant thing in itself.

Remember the book "Code Complete"? I think there was a discussion of that in there. I remember discussing it at length on another forum a few years ago.

What font do I use? In the programming editor, it's Veranda 8. I think that's what it came set to. I seem to have lost my custom settings (the comments are blue; I had set them to green).

Calling with multiple arguments...

Perhaps this is something that authors should keep in mind. How often do we have hash-like bags of named things, as opposed to a known structure? The "param" really is like parameters; just known at a different level.
