This may or may not be beneficial for your particular use-case, but I think the usage can be very nice in Scala. Consider a method “def time(block: => Unit)” or “def time(name: String)(block: => Unit)”, etc. where the usage is like so:

import Timer.time

time(”frameRate”) {
//stuff to time
}

You can still do all of your history bookkeeping in the time method, and will still be able to get the average:
g.drawString(”fps:”+1.0f / Timer.averageTimeDelta(”frameRate”), 10,20);

Just throwing that out there if you like it.
