50#
51# As shown by ticket #3346 above (see also ticket #3298) it is important
52# that a subquery in the result-set be able to look up through multiple
53# FROM levels in order to view tables in the FROM clause at the top level.
54#
55# But ticket #3530 shows us that a subquery in the FROM clause should not
56# be able to look up to higher levels:
