Hi Irv.

I haven't really been following this too closely (and most of it has been
over my head anyway) but the above bit caught my eye. Do you mean that
referencing the elements in a sequence causes this big a performance hit ?
10 - 15% is nasty (and this sort of thing has been required a lot in the
Morfit for EU api I have been working on with Todd. )

If I understand you right, is the performance hit both ways? Does it hurt
just as much to put stuff into an element in a sequence as to get stuff out
of it ?? I haven't noticed such a hit but I'd like to keep such things in
mind if they are there.

Thanks.
