I don't know what you mean.  collect holds numbers.  The code would work
the same if you write collect.push(a) instead of collect.push(this.blah).

Really?  Can you post an example based on the code above?  I don't see
how it can match your description.

> Should "collect" just store the various this values instead?

Impossible to say since I don't know what this code is supposed to do.
What's the problem you are solving?
