Dear Jegan,

i know close to nothing about how expect works and what procs it 
defines. but maybe i can point you to
the right direction, and someone else can help you more specific.

i am pretty sure, edproc is defined in exect in tcl. i would recommend 
to define methods
  Object instproc edproc ...
  Class instproc edinstproc ...
where you get the methods arguments and body in the same way as in 
edproc via introspection and
redefined the proc/instproc after editing.

similar as (1). in plain tcl , you have ...[info vars]..., in xotcl you 
have ...[obj info vars]...It should be possible
with little work to provide a generic xotcl layer for this as well.

i don't understand the problem here, esp. with the "package reqire" and 
"environment variables". if you have a running
script, and you have xotcl already loaded, there is no need to do e.g. a 
package require again before sourcing the script.
We do this all the time e.g. in the openacs environment (openacs.org).
