Some googling brought following link:
http://download-uk.oracle.com/docs/cd/B14117_01/appdev.101/b10807/d_names.htm
I have not parsed it completely, but rule seems simple - inner
scope overrides outer one and no magic on unqualified idents,
if ident is unqualified, it wont be matched to schema, block
or some other qualifier. (well, at least no such magic behaviour
is mentioned.)
