Surely it is.

In these discussions in the list, sometimes it looks like people are
changing environments all the time, in all sorts of code. I may be
very wrong, but my impression is that changing the environment is
seldom done, mainly (only?) in the setup of a module or when running
untrusted code. I would like it to look "ugly", to be easily seen
and found (e.g., "/_ENV"), not to look like "code as usual".
