Ah, but /mine/ does <.002wink>. Anyway, I presume docstrings are
supposed to be relatively short?
Note that I am not comfortable just opening the docstring, because then
the editor colors the rest of my program green until I add the closing
quotes, so I have to type six quotes and three "move back"s just to get
started. It takes nine boring lines of documentation to even approach
the labor implied by opening comment characters. Any
single-character-to-end-of-line syntax is going to make things easier.

nay, it's bigger than a breadbox.

I assume what I'm seeing above is due to the fact that you used the
hated tab key to indent part of the docstring? That wasn't what you
intended, was it? Also, isn't the closing quote supposed to occupy a

That's what I thought. Is there a guideline for how to write those, BTW?

How is reading more Python code going to help? Not trying to be
difficult, really. I'm willing to invest a little to train my stupid
brain to stop complaining. Still wish I didn't have to, though.
