Start of a DSL

I've started refactoring my logic games into a DSL that more closely approximates the English language logic games questions. Here's what I have so far:

#Set up game description
new_game
called "Broadcast"
described_as(
"Seven consecutive time slots for a broadcast, numbered in chronological order 1 through 7, will be filled by six song tapes - G, H, L, O, P, S - and exactly one news tape. Each tape is to be assigned to a different time slot, and no tape is longer than any other tape. The broadcast is subject to the following restrictions:
  • L must be played immediately before O
  • The news tape must be played at some time after L
  • There must be exactly two time slots between G and P, regardless of whether G comes before P or whether G comes after P"
)
with_property "Position"
with_range 1, 7
for_entities "G", "H", "L", "O", "P", "S", "News"

#Create the questions
new_question
described_as "If G is played second, which one of the following tapes must be played third?"
with_fact "G", "Position", :is, 2
determines ["News", "H", "L", "O", "S"], "Position", :is, 3
This replaces the first 70 lines of the game. It sets up the game, and adds all the standard rules, like one-place-at-a-time rules, mutual-exclusion rules, and last-available-position rules.

My goal was to make this read more or less like the English version of the game. One interesting requirement for that has been that it needs to remember context. So if I say "new_question" on one line, then "described_as ..." on the next line, the game needs to remember that "described_as" applies to the new question we just created. I'm doing this by maintaining state. So each action keeps a record of the thing it acted upon, so that the next action knows what the context is. The alternative was to string together actions, like "new_game.described_as(description).with_fact(...)" etc. I didn't like that approach because it looks less like English, which was, again, my goal.

The next step in the DSL will be a simple way to specify the rules. I want it to be close to the English version of the rule, so
"Henry's lesson is later in the schedule than Janet's"
might turn into something like
new_rule "Henry", "Position", :after, "Janet"
Which will then get broken up into the 20 or so rules that that implies behind the scenes.
