TBC, I mean ‘only support #lang' for values of 'lang' that Racket
supports’, or alternatively ‘support #lang for compatibility, but
recommend -*- ... -*- in the Guile manual.’.
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?
