Environment with no parent?

   And, I think, that a better approach is to implement a proper hash
table class

the
current version, which would be environment  - parent), 

Sounds like a good idea. Environments probably need to be *references*
to hash tables plus parent, though.

but the tuit
shortage is devastating on this side of the atlantic (possibly due to
the disadvantageous $/euro exchange rate; I'm sure you all can afford
more of them :-))

I'm sure my publisher will have suggestions for the use of any tuit
that I can get (and they pay in $, notwithstanding the IRS wanting me
to spend my copious free time on wrapping up enough red tape to
prevent them from taxing income which they are clearly not entitled
to do. Puff, pant...)
