Surely you know that in DRL and Java string literals must be surrounded by
quotes. I didn't tell you to omit them from everywhere.

As for a DSL, the author decides where there are quotes. You can define
  [when][]There is ""{blurb}""=...
or
  [when][]There is """{blurb}=...
or whatever.

[condition][]"{sprinkler}" is in same "{room}" and sprinkler is
"{off}"={sprinkler}: Sprinkler( room == {room}, on == {off} )
[consequence][]Turn on the "{sprinkler}"=modify( {sprinkler} ){setOn(true)};


when
   There is fire in "$room"
   "$sprinkler" is in same "$room" and sprinkler is "false"
then
  Turn on the "$sprinkler"
