Is 'set foo="bar"' also possible?

So we really need this? Shouldn't "steam_engine" be
"advance.steam_engine"? What about lists like:

with advance.railroad (
  req [road_building, steam_engine]
  name "Railroad")
?

What is the purpose of the "with" command? Setting? If yes, can we use
"=" for this?

I can also think of objects which are "incomplete". So a "create
unittype.armor" is incomplete until you set certain key properties (it
may also possible that all properties are key properties).

I would like to require "=" always.
