Hi Julien,

Many thanks for the feedback! It is great to hear of your experience  
with the packages. And good, especially, to hear that other people  
besides us are looking at it and using it :)

In this case I think that Joseph's suggestion for search/replace is  
best; you are right that it's slightly slower than using active chars  
but the difference is quite small in practise.

I'll keep your suggestions in mind about a better interface for  
rescan, but can't promise anything at this stage. It's perhaps  
overkill to invent a new syntax to deal with : and _ for a possible  
minority of situations (and in your case I suspect using \lowercase  
and \lccode might also be able to solve your problem). But further  
suggestions if you come up with anything are very welcome! (Example  
code in particular is my favourite :))
