The yield syntax was in Python 2.3, so this isn't indicative of the
problem. You'd actually need to test with 2.5 itself in order to know
what that version complains about.

TTBOMK, Python doesn't have such functionality.

As a note, Python 2.6 has been around since at least 2009, so I think
it's fine to drop support for earlier versions at this point. But I
agree an explanation in the commit message of what exactly makes it
syntactically invalid would be beneficial.
