"#!/usr/bin/env perl" and using multiple environments

I've been considering the potential benefits of using some sort of
self-rolled /usr/bin/env in project development when multiple environments
For instance - if a projects development, testing and production
environments use entirely separate module libraries, it would be nice not
to have to hard code the appropriate 'use lib's.
Now env soes have the ability to let you change specific environment
variables, but if their are lots of changes that's going to lead to a messy
#! at the start of each script.
The alternative I'm considering is to have something like:
Which essentially do the same thing as env, but with a (dev|test|prod)
This way the #!'s become '#!/somepath/env-dev perl' for instance and al;
should notionally be well (and there should be no need for any hard coding
of specific 'modes' within the code itself)
It also means that a general environment can be built up so the
env-(dev|test|prod) can be used to construct all environments, not just the
Anyone seen this sort of thing done, have any thoughts on the matter?
