I'm wandering around trunk looking for slowness.

are constant distractions which I've meant forever to fix anyway, such
as the importing of collection.mutable._ (or any other package with lots
of reused names.) Why is this relevant to performance? Well,

  var x = new HashSet[Int]

What's that? What does 'x += 1' mean? These are questions we can all
live without.

There's almost nothing left which references HashSet or HashMap or Stack
or other ambiguous classes without a qualifier: I can finish trunk but
I can't keep it clean on my own. (Where should I be writing this stuff
down, I wonder.) No review.
