Well, it is not as much an interface rather than exposed internals. There is no reason, for example, that one needs to write (let ((process-environment (copy-sequence process-environment))) (setenv ... ) rather than (with-local-environment (setenv ... ) However, designing, implementing and _mandating_ something like the latter takes time and several releases. -- David Kastrup
