Hello, I would like to replace a core binding. I know that I can define a module like this:
(define-module (foo))
(define-public (copy-file a b)
(display "TODO: implement file copy\n"))
And I can later use it
scheme@(guile-user)> ,use (foo)
scheme@(guile-user)> (copy-file 'a 'b)
TODO: implement file copy
But! I would like to replace the copy-file globally, for all modules, without
the need to explicitly import it. I guess I want something in the spirit of the
`install-suspendable-ports!', so that I could do something like:
scheme@(guile-user)> ,use (foo)
scheme@(guile-user)> (install-better-copy-file!)
I could patch the Guile itself, but I would strongly prefer to avoid that, for
obvious reasons. So, is it possible to achieve what I want, and if so, how?
Thank you and have a nice day,
Tomas
