Hello list.

1) Catching up a bit, it occurs to me that

shell%> chuck --start `while(true) 1::second +=> now;`

has been superseded by

shell%> chuck --loop

; correct? Does ChucK any longer accept subprocesses or so, from the shell?

2) Also if anyone cares to distinguish or give an example for

--callback
Utilizes a callback for buffering (default).

--blocking
Utilizes blocking for buffering.

then I'm much obliged as this is unfamiliar in some respects to me.
