I have this simple function...

function {
     #local normvec = vnormalize(x,y,z);
     vlength(normvec)+f_noise3d(normvec.x,normvec.y,normvec.z)-1
}

I'm trying to get the normal vector of the current x,y,z coordinate being
tested, but it appears to think i'm referring to the variables x=<1,0,0>,
y=<0,1,0>, and z=<0,0,1>, so it gives me the error "Parse Error: Expected
')', , found instead" on the line with the "local" statement.

Is this a bug, or do I need to do this some other way? Trying
#local normlen = sqrt(x^2+y^2+z^2)
also caused an error.
