Comment (by afb at macports.org):

 And of course, having to remember to type "array_unset_env" instead of
 "array unset env" isn't much easier than remembering to call unsetenv. And
 since unsetenv requires pextlib to be loaded first, combining the two into
 a wrapper isn't possible for all uses either. So I think we'll avoid the
 whole wrapper idea.
