Re: Registering an indexer for multiple types

If you're going to have a custom zcml registration, shouldn't that also do
the wrapping?  I guess that would get rid of the "advantage" of only one
zcml registration, but it would also avoid the need to use the decorator at
all.  Perhaps both a zcml configuration and a corresponding grok directive
would satisfy both those who want to do the registration from python and
those who wish to keep it separate.
