[Zope-Checkins] CVS: Packages/ZConfig - datatypes.py:1.1.2.18

[Fred L. Drake, Jr.]

Update of /cvs-repository/Packages/ZConfig
In directory cvs.zope.org:/tmp/cvs-serv20599

Modified Files:
      Tag: zconfig-schema-devel-branch
	datatypes.py 
Log Message:
Change the helper classes so that instances are valid conversion
functions.  We still use bound methods for efficiency, but doing so is
not required.
