Re: Case sensitivity in modules?
It surprises me that -g doesn't work, especially since this does:
[1]ptg$ mzscheme -g
Welcome to MzScheme version 200alpha14, Copyright (c) 1995-2002 PLT
Identifiers and symbols are initially case-sensitive.
> (module modtest mzscheme
(provide foo bar)
(define foo (lambda () (equal? 'hello 'hello)))
(define bar (lambda () (equal? 'hello 'Hello)))
)
> (require modtest)
> (foo)
#t
> (bar)
#f
Perhaps you can't rely on -g for making program text case sensitive since
it may be compile to bytecode without -g, though it doesn't seem like the
case here.
It's probably better to use #cs(module modtest ...) for a case sensitive
module anyway since the module author knows better if it should be case
sensitive or not.
