have not had trouble with the inspectors.

When I first started playing with MASON, I did so exclusively through Scala
with the MASON jars in the lib directory of a sbt project. See: for my first attempt with Scala and
Mason. (It was tried, put online for some friends to read, and never really

As a lot of people have said, (most visibly Yammer:, Scala can be
unexpectedly and painfully slow in some places. For an agent-based modeling
library, I would think you *really* do have to pay close attention. From
(my) perspective as a library user, I care way less about efficiency than
readability, in my code anyway.
