Well, the reason I say that is because the experience will be necessary in
the future, when you come across more difficult problems that trace() is
unable to solve. (For instance, if you have two spheres' initial positions
and velocities, at what time will they collide? That can't be solved with
trace, because both objects are moving.)

IMO, trace() should be used only in cases where a mathematical solution is
impossible or impractical, like finding the intersection of a line with an
isosurface based on the random noise function.
