Natural Language
I have problems with Inform 7 being described as a natural language.
In this instance, yes, perhaps:
Definition: a person is dying if it was last fed way too long ago.
But this is just taking the piss:
Before burning something with a new strikable-match (this is the prior lighting rule):
say “(first [if the player does not carry the second noun]taking and [end if]lighting [the second noun])[command clarification break]”;
silently try striking the second noun;
if the second noun is not flaming, stop the action.
