`interaction-environment' is mutable.  I think this is clear

from the fact that immutable environments are explicitly

described as such, but we could emphasize it in the text.

Consequently, the result of using `load' and `eval' on code

with top-level definitions in anything but `interaction-environment'

is unspecified.

This has come up before.  There are use cases for both

mutable and immutable environments, but we've only provided

one mutable env in the small language.  WG2 will provide

a library for more configurable mutable envs.
