The 'Bin' stretch exercise in 'Induction' requires re-defining code from previous exercise

[michaelpj]

For a reader who is doing the exercises inline, you have defined inc/to/from in the 'Bin' exercise in 'Naturals'. There is another exercise in 'Induction' that uses 'Bin', but at the moment you have to redefine the type and functions before doing the exercise.

A solution would be to import the 'Naturals' module, but you can't in fact do this as there are conflicting bindings.

Just so. The present situation is annoying, but I don't know of a better approach. Short of someone suggesting one, I propose we should close this issue.

Maybe it could just have a note to make this obvious.

OK. Can you draft a pull request with a suitable note?
