Whoops -- forgot to send my response to this.

I was less worried about explaining the concept of multiple return
values, and more about naming what the return values were: that the
first one is the result information, and the second is the parsed
test.

That being said, it's reasonably obvious from the types in this case,
so I'm okay leaving this as-is, though in general I'm wary of tuples
when the order doesn't matter, and a struct-style thing (with named
members) fits that better.

I'm no Python expert though, so don't let my whinging get too much in the way.
