But for a transaction, it is 'with session', not 'with begin_session'.

With 'begin_module_init' I would have no idea what 'm' was.  With
Brett's 'module_to_init' I have an intuitive idea about what 'm' is.
And if 'm' isn't a module, then module_manager would be better.

(Note that I haven't grokked what Brett's context manager is actually
doing/returning, I'm speaking here as an ignorant reader of someone
else's code :)
