I realize I somewhat misrepresented my own proposal; it's closer to `export
thearr ...`, `importas -s files thearr` and `importas -s newfiles thearr`.
Call it envglob; elglob can even be implemented on top of it via
elgetpositionals -> envglob -> importas with intentional serial
substitution.
Nevertheless, the pattern of defining two variables with the same contents
persists, and this variant requires more careful handling of `-u` in
`importas`. I honestly find `define`-renaming (and Emanuele's proposed
extension) a more maintainable pattern, and it's the one I use in my own
scripts.
