 * An identifier referring to a method name, along with an instance for the call.

 * in valid programs.
 *
 * Method calls are only supported on effect-child types, and they all resolve to intrinsics
 * prefixed with '$', and taking the 'self' object as the last parameter. For example:
 *
 *   uniform shader child;
 *   ...
 *   child.eval(xy)  -->  $eval(xy, child)
