The code tried to generate Show instance for a function.
I don't know where it used to come from but it's not there
anymore. Build fails as:
[48 of 49] Compiling Hakyll.Web.Paginate ( src/Hakyll/Web/Paginate.hs, dist/build/Hakyll/Web/Paginate.o )
src/Hakyll/Web/Paginate.hs:40:17:
No instance for (Show (PageNumber -> Identifier))
(maybe you haven't applied enough arguments to a function?)
arising from the second field of ‘Paginate’
(type ‘PageNumber -> Identifier’)
Possible fix:
use a standalone 'deriving instance' declaration,
so you can specify the instance context yourself
When deriving the instance for (Show Paginate)
Change drops Show instance as it's not very useful.
