I was able to follow the documentation that much.  ;-)

this leaves me with (yet another) question.  How do you treat ctx.locals as a 
dictionary/array/whatever makes the easiest to programmatically create entries 
and search on them?  I remember experimenting very early on and it didn't seem 
like __getattr__ and family were present.  Am I just too sleep fogged?

I've been playing around with locals.__dict__  to try and get a feel for what's 
there and at least I can see all of my spamtrap tokens but I wasn't able to 
access them as .local.xxx variables.

  for entry in context.locals.__dict__:
             if entry.find("token") <>-1:
                 syslog.syslog(entry)

yielded:

I definitely need some sleep.  I'm up early in the morning to take care of an 
elderly aunt in our early summer heat and go purchase her air-conditioning.
