Dear all, 
I'll try to be short: do you know if its possible to define a cell containing 
a List of Maps (e.g. a list of environments)? If not, do I have to maintain a 
list of numbers and a separate map from numbers to "environment" cells (each 
one containing a numeric id and a Map)?

I see the technique you used in IMP++ ("storing" the previous environment in 
the computation and then restoring it after the content of the block has been 
executed). It looks great, but in my case I sometimes need access to at least 
the "global" environment (the first that was stored stored), and I don't see 
how to do it in that case (that's why I'm considering using a list).

Btw, I'm finding K very stimulating.

Regards, 
Daniele
