This is now implemented, as:
select mapElement
from Foo foo
join foo.map mapElement
where index(mapElement) = 'foo'
The index() function may even appear in the select clause.
Note that path expressions with [] may still not appear in the select or from clauses.

mapped to collections, something like this:
if names is a list:

Null should be returned if either lookup fails.
