`last` usage

I'm trying to use last function. It is ambiguous with Prelude's last, so I'll hide it:
import Prelude hiding (last)
Then it compiles, but it does throw an exception in runtime:
Uncaught ReferenceError: Main$last is not defined
So either there is a bug in the library or I'm doing something in a no-good way.

Probably a bug specific to hiding Prelude imports. I'll check it out, thanks!

Quick fix is to change JQuery.hs to import Prelude hiding (last). This seems to happen only when an imported module imports Prelude.

Extremely high effort/LOC on that one :) please verify that it works for you and I can upload it to hackage.

I verified by uninstalling fay package, cloning fay, building it, installing and compiling my example, seeing that it works! Thanks
