Ah, so it was in the summaries.  I totally understand about other

Interesting.  I'd personally be too nervous to keep AutoCommit off  
for that wide a scope, but I like the idea.  I basically went with  
the approach I did because it's basically the same thing that sri did  
in Maypole::Plugin::Transaction.

Agreed.  What about way to specify a particular action as being a  
single transaction?  Something like a keyword after the Global/Local/ 

sub do_atomically : Local Transaction {
     my ( $self, $c ) = @_
     # Do some stuff...

I was tossing that idea around in my head and wasn't quite ready to  
consider it (maybe for a future release), but now's as good a time as  
any to discuss it.

What I really need to do is bring this up on #catalyst, but they  
don't keep western U.S. hours over there (I'm in California).  By the  
time I get home where I can get on IRC, most of #catalyst has gone to  
bed.  So I just read the scrollback.  Some day I'll stay home and  
chat.  :-)
