[chuck-users] variables and memory

Eduard, Kassen,

Kassen, he's right!  It is freed.  At least, with his addition, the
code we posted stayed steady in the memory dept.  Very low usage and
never changed.  Without that line, it eats up memory until it's all
gone.

while ( true )
{
        for( 0 => int i; i < 100; i++ )
        {
                int var1; float var2[10];
                // do things
                1::samp => now;
                NULL @=> var2;  // this frees memory.
        }
}

Well, that's very interesting...  I have a lot of code that I want to
go back over and see if it uses less memory if I judiciously set
object references to NULL when I'm done with stuff.  There's your
destroy method, Dimitris!  Όλα Καλά!!

I think actually that this might solve the problem. (I hope that it's not only objects/arrays that you pass by reference in ChucK, I'll have to check the manual...)

For example recursion; we can use recursion (it's even used in the examples) but we tend not to. For me part of the reason there is that I fear the amount of garbage. For practical things I can re-write most things linearly so it's no big deal but a recursive approach might be extremely interesting on a compositional level.
