I think you must be thinking in #timeToRun.
No, but you saying that reminded me of where I saw it. It's in the
Time class.
ms := Time millisecondsToRun: [ do some stuff here ]
Using this on the code below, the comma approach took 8478
milliseconds and the stream approach took 185 milliseconds. Big
difference!
About that... In VisualAge there are the EsbTracer and EsbSampler,
which allows you to meassure the time that involves every message
sent. It's useful to tune some code... But don't know in Squeak. Any
ideas?

That reminds me. I know I ran across a method that runs a block and
then tells you how long it took. Anyone remember what that's called?

speed is the reason for the stream approach. The #, approach copies
the first string once for each #, send.

Don't know of any but then I'm not an expert.
