[chuck-users] Why doesn't this work?

[Matt B.]

Hey guys

I'm trying to do a simple chuckle, but something's going wrong when I
try to set s.freq...

SinOsc s=>dac;Phasor
p=>blackhole;p.freq(2);while(1){Math.sqrt(1/p.last())*100=>s.freq;10::ms=>now;};

If I dump "Math.sqrt(1/p.last())*100" I get floating values as
expected between 100 and 700, but when I chuck it to s.freq, no sound
is output, and s.last() is always 0.

Am I missing something or is this a bug?
