[Biopython-dev] New test_Phylo.py test on Python 3

[Eric Talevich]

Thanks, Peter. The build bot is pretty handy!

My fix was here, for the public record:
https://github.com/biopython/biopython/commit/8edd552b72a31179cd53eb1493ac5462f7fb8f7c

Lambda expressions like the one in test_Phylo.py are supposed to Just Work,
since manually handling all the edge cases for comparisons is tedious (or
impossible, since try/except statements aren't allowed in Python's lambda
expressions). So I fixed the way Bio.Phylo wraps lambda expressions,
instead.
