That would be great.

If a macro is a sub-layout, why not just call it a sublayout.

What is "COW"?

Great, can we have paramenters/return values passed to/from the
sub-layouts/elements?

Like, here is a led and resistor, we want to feed it with 12V, 5V etc.,
or is that more a job for gschem?

Another cases could be:
. here is a sub-layout, but we want 1 mm clearance
. drill/thickness ratio should be 2.4 for this connector
. ohh, you cannot have 5 mm clearance for the connector
. here are five output relays, it should be a relay every 13 mm
  along this line.
. here is a trace, we want it to be able to handle 12 A
. this stripline should be 50 Ohm
. this serpentine should have a trace length of 27.4 mm
