> I have some rules with very long LHS expressions.  I'd like to split them across multiple lines for readability.  However, the parser has limited support for breaks.
> These work:
>  
>   when
>     ObjectTypeName( p0_exit_epoch > (RUM.now()),
>                     p0_exit_epoch > (RUM.daysAgo(7)) )
>     variable :
>       OtherObjectType($rlis : rlis -> (RUM.countFieldsMatching($rlis, "state", "dev-maybe") > 0))
>  
> These don't:
>  
>     variable : OtherObjectType($rlis :
>       rlis -> (RUM.countFieldsMatching($rlis, "state", "dev-maybe") > 0))
>  
>     variable : OtherObjectType(($rlis : rlis ->
>       (RUM.countFieldsMatching($rlis, "state", "dev-maybe") > 0))
>  
>     variable : OtherObjectType($rlis : rlis -> (RUM.countFieldsMatching($rlis,
>       "state", "dev-maybe") > 0))
> While I'm at it, I'd love to have support for multiline expressions in DSL files, but I can imagine that would be a bit harder...
