Thanks.  Any idea how to deal with ABCs?  It's sufficient to use a
simple class, but I want to expose an ABC in 3.0 as it will make it
easier for others to extend.

Unfortunately, "metaclass=" is a syntax error in 2.6 so the following
still fails:

from sys import version

if version.startswith('2.'):
    class Matcher():
        pass
else:
    class Matcher(metaclass=ABCMeta):
        pass
