Oh, yes. That looks great! Also seems to work with OverloadedStrings

Oh, never mind. In this case, I guess I don't need an extension at all!

Ugh... I take back the never mind. So if I replace Prelude with an
alternate definition, but don't use RebindableSyntax, and then hide
the base package, GHC still uses fromInteger and such from base even
though it should be inaccessible. But if I do use RebindableSyntax,
then the end-user has to

This is working now. Trying to use -XRebindableSyntax with
-XImplicitPrelude seems to not work (Prelude is still not loaded) when the
exposed Prelude is from base, but it works fine when the Prelude is from a
different package. Counterintuitive, but it does everything I need it to.
Thanks for

I'd like to implement an extension to GHC to offer a different
behavior for literals with polymorphic types. The current behavior is
something like:
Oops, when I wrote this, I'd assumed it was possible to export
defaults from a module, like an alternate Prelude. But it looks like
they only affect the current module. So this whole thing depends on
also being able to either define defaults in an imported module, or in
options to GHC.
