"serialize cyclic structures"

Trying to console.log an object and I just get:

TypeError: JSON.stringify cannot serialize cyclic structures.

We’re using MooTools and I think it might be something to do with trying to stringify a MooTools Class.

thanks @nathanboktae! I fixed my problem by using this:

    describe('functionalityToTest', function() {
        var stringify = JSON.stringify;

        before(function() {
            JSON.stringify = function(obj) {
              var seen = [];

              return stringify(obj, function(key, val) {
                 if (typeof val === "object") {
                      if (seen.indexOf(val) >= 0) { return; }
                      seen.push(val);
                  }
                  return val;
              });
            };
        });

        after(function() {
            JSON.stringify = stringify;
        });

        // tests go here
    });

Yes it is.
