how many types would a 'g' type type if a 'g' type would GType?

It is used for the signature header, so it is a multiple-type signature 
there. However, I think it isn't allowed to have multiple types when 
it's the signature of a variant. Don't remember for sure. If so, it 
sounds like for your usage you can just assume the signature of a 
variant has only one type in it.

For the glib bindings generically perhaps you could just marshal as a 
GType if only one type, and as an array of GType otherwise, and app 
authors can just handle both cases?
