Could also allow:
Cheese( name = Person( location == "london").favourCheese )
Can also use this to constrain on the fact itself, instead of just a field:
Person( cheese = Cheese( type == "stilton ) )
This could be use in config options:
Call( duration < CallConf().minDuration )
But as Edson pointed out it is open to abuse and misunderstanding, how
long till people do:
Call( duration < CallConf().maxDuration, duration > CallConf().maxDuration )
Which is more like doing the following which has cross product issues:
CallConf( $maxDuration1 : maxDuration )
CallConf( $maxDuration2 : maxDuration )
Call( duration < ,$maxDuration1 duration > $maxDuration2 )

I've been thinking of an idea to make rules more expressive, its just
syntax sugar at the parser level, but thought i'd ask feedback - if
anyone with antlr skills wants to make this work, let us know :)
Instead of doing:
$p : Person($favouriteCheese : favouriteCheese )
Cheese( name == $favouriteCheese )
We should allow the following:
$p : Person()
Cheese( name == $p.favouriteCheese )
We could take this further and in places where a pattern is not used
elsewhere allow:
Cheese( name == Person().favouriteCheese )
