Two string comparisons in same expression fails

[goodwithgit]

I have an object defined thus:

define Value {
    id : null,
    v : null,
    constructor : function (id, value) {
        this.id = id;
        this.v = value;
     }
}

I'm asserting a fact like this:

s.assert(new Value("xyz", "abc"));

Then looking for it in a when clause like this:

v4 : Value v4.id =~ /xyz/ && v4.v =~ /abc/;

The above fails to trigger the rule. The following does trigger the rule:

 v4 : Value v4.id =~ /xyz/ && v4.v ==  'abc';

For some reason, two string comparisons in the same rule don't want to play nice.

After some investigation there is an issue with parsing regexps in the constraint grammar which does a greedy match on the first regexp. Im working on fixing the parser for the regexp and will have a fix soon.
