Re: gEDA-user: moving slotting to pcb?

I think I mentioned at one point that pcb could do the slotting at
least itself, by noting which physical pins were already assigned to
logical pins, and just preserving that.  It would send that
information to gnetlist each time, so gnetlist could allocate the
remaining slots.
While this was a misconception (mostly) (which John D. clarified ;-), having a set of symbols all working on the same refdes is a form of slotting that works this way. Iirc, eagle has packages, that provide symbols foo_a, foo_b,... e.g. for quad-NANDs. I got no problem, if later stages in the workflow assemble multiple symbols to a
physical part. And tbh, I don't like the mechanism with the slot attribute.
Having a separate power-connector symbol belonging to a split up logic part,
that you MUST place instead of a hidded net-magic-attrib, looks better to me as well.
