[Mapserver-dev] layerObj resultcache?

[sgillies at frii.com]

Hey, just checking in on email before my return ... protecting
the resultcache from mapscript was a mistake.  I didn't mean to
change the usage and think that we should revert to rexposing
resultcache for 4.2.

In the future, what I'd really  like to see is a cursor-like
class for queries.  Aren't we all using something like this
with the DBI modules of our favorite languages?

    cur = the_layer.cursor()  # implicitly opens layer
    cur.queryByRect(the_rect)

    while 1:
        result = cur.fetchone()  # or something like that
        if not result:
            break
        ...
