#1 Person( age * 2 > $anotherPersonsAge + 2 )
#2 Person( addresses["home"].streetName.startsWith( "High Park" ) )
#3 Person( isAdult() )
#1 does not compile: Unable to build constraint as 'age * 2' is invalid : [Rule name='exa1']
#2 works - although I'd very much prefer not to be swamped with MVEL extensions unless I ask for it.
#3 does not compile: Unable to Analyse Expression isAdult():
[Error: no such identifier: isAdult]
[Near : {... isAdult() ....}]
Neither rule name nor line number is provided.
Would it please be possible to have a precise statement what one can write as a constraint?

This was also important for us to start to move towards a
single consistent grammer for both the "when" left hand side and "then"
right hand side.

It seems that example #2 increases the grammar gap because the constraint expression can certainly not used on the RHS.

As previously we had to document the restricted
limitations of a field constraint on the LHS compared to expressions
used inside of an 'eval' or used on the RHS.

I'm sorry, but I do not understand the meaning of this sentence. What does it mean, please?
