Re: TkDesk-code digest, Vol 1 #8 - 1 msg

One trick I use to get around that sort of thing for my Odie library is 
to only call Itcl through a wrapper function. I use odie::class and 
odie::body, which only call itcl after performing some sanity checks. 
(Like not re-creating an existing class.) My wrappers also do neat 
things like auto-document the classes and methods.

I'm not sure how useful that would be at this stage in the game, but you 
never know.
