Title: Promise.as

Hi Robert,

Not sure what you think about this, or whether as3-signals is even an on-going concern of yours. I have added a Promise class. I'm not sure if the name is correct, but it's a simple pattern that I find myself using quite a lot. Essentially it's a one-time dispatcher to which if a listener is bound after the dispatch, it immediately receives the previously dispatched data packet. It seems to me that it would be a useful addition to the toolkit. I'm interested to hear what you think.

Regards,
Alec
