The point of this is to tell the compiler what language it needs to parse,
if not the default (Scheme).  Using `#lang pascal' or `#!lang pascal' 
allows
the compiler to figure this out in the first few characters read. Using
`-*- lang: pascal -*-' might require the compiler to read a lot of text 
(not knowing
if what text is comment or not) to determine if language has been 
specified.
For the `-*-' based design, is there a maximum number of characters to be
read before deciding?
