Обсуждение: Var->sublevels_up

I can't figure out how to properly do the the Var->sublevels_up search in the
existing code, partly because I can't figure out what it is doing.

It will take me a few days more to do it.  I just can't look at the code
anymore.

OK, I think I have a handle on it now.  Should be two days.

                                                     ^^^^^^^^^^^^^^^^
It says what range table should be used to find Var' relation.

My problem was the ParseFunc really does much more than handle
functions.  It handles:

    colname
    rel.colname
    rel.colname.func
    sum(colname)
    sum(rel.colname)

and probably much more than that.
