Internally generated and user submitted anonymous blocks can't access temp tables from the surrounding scope

While the blocks are resolved against the surrounding scope, when executed the procedure plan shields them from seeing the higher level scopes just as when a real procedure is executed. This results in temporary table 'temp' not found exceptions, for example with a non-simple view v and the delete:

delete from v where e2 = (select max(e2) from temp as z where e3 = z.e3)
