RE: Is this the Free-Format that we asked for? (And are we sure?)

[Joel Fritz <JFritz@xxxxxxxxxxxxxxxx>]

Here's one from the Python tutorial:

a, b = b, a + b

This means:
If a = 1 and b = 2, after this operation a = 2 and b = 3.  

It makes sense if you know the rules, but you do need to know which rules
apply.  And, worst of all, you have to remember it.
