I disagree with this approach, as the same function should be
responsible for all changes with a particular purpose.  If you really
want an Unset, I would suggest something along the lines of:
Unset(GROUP(foo)).

However, I am very leery of an Unset application used in combination
with variables, as that breaks some assumptions with argument stacks.
