Yup.

A typical comment I came across yesterday in a comment for loadEx in  
ServerStub.py:

     # Return current data for oid in version, the tid of the  
transaction that
     # wrote the most recent revision, and the name of the version  
for the
     # data returned.  Versions make this hard to understand; in  
particular,
     # the version string returned may not equal the version string  
passed
     # in, and that's "a feature" I don't understand.  Similarly, the  
tid
     # returned is the tid of the most recent revision of oid, and  
that may
     # not equal the tid of the transaction that wrote the data  
returned.
