How is 'provide' and 'require' implemented in existing CL-implementations?
I would like 'require' to search for the compiled file first, and load it if
it's found. Xerox Lisp has a 'require' that doesn't bother about compiled
files. This makes it almost necessary to use the InterLISP function 'FILESLOAD'
and that will make programs less portable.
Let's say I have a file submodule that does the following:
(provide 'submodule)
;;; rest of file
Then say I compile this file, getting a submodule.fasl (or whatever extension
is used). If I have another file with these statements:
(provide 'mainmodule)
(require 'submodule)
;;; rest of file
I would like this file to load submodule.fasl, not submodule.lisp. The fact
that the extension for compiled files is not stated in CLtL, makes it
impossible to write (require 'submodule 'submodule.fasl) or something like
that.
