Subject: Raise an exception right away if the Python version is unsupported.

As suggested by @DorianScholz in pull request #14.

Use 3.2 as minimum version since that's what I originally targeted. I
wonder if there is an easy way to track which features the code is relying
upon to keep this up to date.
