This is no valid code, not even for megapov.  Have a look at the
documentation and the sample scenes for correct declaration of functions
and use in isosurfaces.

You probably want something like:

#include "functions.inc"

#declare MySphere = function { f_sphere(x, y, z, 1) }
#declare MyTorus = function { f_torus(x, y, z, 1, 0.3) }

isosurface { function { min(MyTorus(x, y, z), MySphere(x, y +0.5, z)) }
