Relying on side effects can be dangerous, though.

There is a way, but I find it somewhat ugly/hackish. But Shane uses it
in CookieCrumbler, so it must be good ;)
You'll be working outside the REQUEST transaction at that moment, so pleaseIn fact, the database connection might already be closed. If you need to read or write the ZODB, you might have to open a private connection and close it before returning. Ugh.
keep that in mind when modifying objects.
