> The compiler accepts constraints such as
> {code}
> Person( fullName contains 'Jr' )  // should be fullName.contains('Jr')
> {code}
> Interestingly, MVEL evaluates it as the string operation "contains", but 
> once the constraint is jitted it is again evaluated as a collection operator.
> That is, a rule such as:
> {code}
>   when
>     $s : String( this contains "foo" ) 
>   then
> {code}
> with inputs "foo1" .. "fooN" effectively fires an unpredictable number of times before starting to fail silently
