A command, similar to the roguelike \"exchange\" would be nice. I
could see two directions for this, and possibly a way to put them together.
\"exchange\", with no arguments, would simply exchange the item
wielded in the right hand with that in the left, useful for switching what is
used offhand. As well, \"exchange <item 1> and <item
2>\" could exchange a wielded item for one in the inventory. This
would allow a command alias for something such as \"exchange scalpel and
longsword\", rather than the more lengthy \"remove
scalpel\"-\"wield sword\".
