the current environment inherited by the closure that is assigned to Blah
is the original global environment, since you only changed the current
environment to newgt *after* the assignment to Blah.  in order to inherit
the new environment, you would need to move the closure assignment after
the call to setfenv().

chapters 14 and 15 of Roberto's book go into more details on this stuff.
