Hi,
I have seen the ticket in JIRA. But to be sure to be understood, I
give an other example.
I would find a way to write this DRL code :
Person( age ( (> 30 && < 40) || (> 20 && < 25) ),name == 'DOE' )
In DSL code like this :
There is a Person with
((- age is less than 40
- age is more than 30)
or
(- age is more than 20
- age is less than 25))
- name is 'DOE'
Thanks andy for the ticket post :)

Ok, i took the liberty and created a ticket for this.

All,
This is a limitation of the current DSL engine implementation.
The
problem is not really the "or", but the "-" implementation. The
LHS and RHS
of a DSL rule are processed line by line, so, to allow the
behavior you are
requesting, we will need to implement some look ahead mechanism
with smart
interpolation that does not exist today.
I'm not sure if someone already opened a ticket for that, but
in case
not, may I ask you please to open? We will look into supporting
that in the
future.
