This whole discussion started about the difficutly of using the result
of maparg(). As far as I can see you only provide a function to get more
mappings, it doesn't help with disabling and restoring mappings.
Dealing with that is not easy at all (dealing with modes,
escaping/unescaping, etc). I would not want every plugin writer to
re-invent the wheel.
The basic discussion first need to be held is whether to refer to a
mapping just by its LHS (plus mode) or a unique handle can be used. The
latter is useful if we disable a mapping but not delete it, it can then
be shadowed by another mapping.
We probably also need some kind of re-enable or restore function, that
takes the result of maparg() and defines a mapping with it. That avoids
string manipulation and using :exe (this is tricky because of the way
mappings need some characters to be escaped).
