Can I use turbulence inside a function declaration? I know of
the vector function vturbulence but I don't think I can use
that inside a regular function.

What I'm looking for is something like

function {f_spherical(x+f_turb_x(lambda,omega,octaves,x,y,z),
                       y+f_turb_y(lambda,omega,octaves,x,y,z),
                       z+f_turb_z(lambda,omega,octaves,x,y,z))}


which should in effect yield the same function as

function {pattern {spherical turbulence 1}}

but would allow to make turbulence strength dependent on
location, e.g., for a media with non-uniform turbulence.

There is a function vturbulence.
