Chris probably didn't mean that. All that "magic" means in this context is that
%ENV is subtle and quick to anger :-)

I don't disagree that each() and exists & so on should work correctly on
%ENV, but that requires changes in the hash code that I will not make by
myself without consulting with p5p.
