Yeah, I already do use the modern completions a lot elsewhere.  I'm just 
trying to get this to work here :-)

Huh, sounds like it's worth a bug report.  I don't have any mention of 
compctl in my compinit but maybe I got lucky.

It's being set by the completion system, I guess.  I inserted a 'set' 
into the completion and grabbed the variable which contained the 
function name whose argument was being completed.  In any case, if I can 
do without it using compdef, I'm all for it...

Works great, thanks, though I now need to move the above to below where 
I call compinit; that may break a lot of users of virtualenvwrapper.
