I spent some time yesterday thinking about how we could reduce and untangle all the conditional logic in building parser-based IF in Decker, and I came up with a few thoughts. If we represent rooms within a game as cards, and objects within those rooms as widgets, we could use Decker's ordinary event-sending mechanisms to drastically reduce the amount of repeated logic, so that instead of having to write:

 # (imagine this surrounded by a huge pile of other semi-related repetitive logic)
 ...
 if (obj~"battery")&(verb~"lick")
  printf["tastes sparkly!"]
 end
 ...

It's only necessary to write an event handler on the "battery" widget:

on lick do
 println["tastes sparkly!"]
end

And everything is broken up into tidy logical pieces instead of one gigantic script.

Give this a spin and then poke around inside to see if it provides any useful ideas:
