I don't see a problem too, but we didn't find a compromise with this
syntax, so I left it. It is true, so current implementation of FOR
stmt is really baroque and next argument is a compatibility with
PL/SQL. My idea is so FOR stmt will be a compatible with PL/SQL
original, and FOREACH can be a platform for PostgreSQL specific code.
