Hi, Michael: Ah! Ok, thanks!

Hello Greg, $ is the cast operator, documented here http://chuck.cs.princeton.edu/doc/language/oper.html In the example you have posted, the specific class of reference.get(i) is not known, so it must be cast to Interval. This is a pattern similar to how collections in java were used before generic types were added to the language. michael On Thu, Nov 21, 2013 at 11:29 AM, Gregorio Gomez wrote:

Hello, everybody:

I've been looking at Michael Heuer's (most excellent) LiCK library. He uses an idiom that I don't see documented:

intervals.get(i) $ Interval @=> Interval interval;

from Arpeggiator.ck, line 35 https://github.com/heuermh/lick/blob/master/Arpeggiator.ck

What does $ do?

Of course just because I don't see it in the documentation doesn't mean it's not there, so please feel free to point me to the docs if I've overlooked it.

Thanks! Greg
