Dear Lukas,
your rewrite of MAChainAccessor provoked some panic here!
Just to let you know that I had written a couple of chaining and
unchaining operaterations, which I use for mapping a flat db query into
a magritte model. It allows me to treat a chain accessor as a kind of
stack as the model is traversed.
These are
#last
#chainTo:
#chainUnlinkLast:
I thought that you might be interested in adopting these (now they are
fixed for the latest) as utilities into MA-Model. If you are interested
then you will find them in the latest Magritte-RDB package in magritte
addons.
best regards
Keith
