Scala Meeting report 2011/09/20

I was very pleased with Eugene's post this week about macro's. As an
avid community post reader (much less a contributer to be honest), I
enjoy reading updates about the direction Scala is taking.

With that in mind, I'd be very interested seeing similar efforts with
respect to eg. virtualized pattern matcher (what can we expect with
respect to that) and also the intriguing mentioning of "dynamic
typing" (Nada).

In general, I would love to hear more of what is brewing at EPFL.
