With guile, the undocumented 'make-fresh-user-module' procedure probably
does what you want.  It constructs a new top level for the thread of
execution which calls it, which is unique as against any other top
level. Whether it is what you want depends on what you mean by an
"environment", which is not necessarily the same as a "namespace".  If
you are after a new namespace, make-fresh-user-module should do it.
