Unfortunately it isn't that easy.  This would only work for one object, but not
if you want to expect on several objects at once via '-i'.  It most certainly 
could be done in some way but would add a lot of complexity in terms of
semantics due to hidden parameters.  If you want such a thing, you are always
free to order your pattern-callback-list the way you want.

I still like Tcl, but only for its original intent, namely bringing an 
easy-to-understand-and-learn config scripting language to any application
with a minimum of fuss.  But I don't want to write large applications in
it anymore due to the quoting hell you get into when you want to smuggle
regexps with variables in them through the parser.  And the parsing-at-runtime
didn't help either...

BTW, if anybody can think of requirements for the Expect rewrite, feel free 
to throw them my way, I'll collect and forward them.  And yes, using the 
scripting languages regexp engine is already on the top of the list...
