Returns the old depth of the context (that is, the depth the CV would be at after this context returns).

  depth
   $depth = $ctx->depth;

Returns the actual depth of the context. This is inferred at load time by considering the "olddepth" of the next inner-nested call to the same CV, or from the actual "depth" of the CV is no other call exists.
