scm_system_environment

[Mikael Djurfeldt]

Hmm...  What is a "system environment"?

An environment is a mapping from names to locations.  But here, we
want a hash table containing all symbols in Guile, right?  It
shouldn't map these symbols to locations.  (Or am I missing
something?)

So, I propose that we switch to a better name.

Also, we could actually consider using a more efficient
representation, for example a weak vector...

Best regards,
