[ZODB-Dev] Fwd: [Zope3-dev] directory hierarchy proposal (Martijn Faassen)

[Jeremy Hylton]

We also ran into another potential problem when trying to merge the
BTrees into a single module namespace (where zope.btrees.OOBTree is
a class).  There are a bunch of functions like union() that are
specific to a particular flavor of btree.  It's not obvious what to do
with them if they get merged.  Maybe oonunion, but the namespace gets
pretty fully.
