GVariant is exactly this way too.  The type system even explicitly 
supports this concept with the '?' wildcard: it matches any simple type 
(ie: no containers).  This was done because I wanted to be able to write 
"a{**}" but that would have been invalid: now you can write "a{?*}" 
instead to mean "any dictionary entry type".
