Hello, should the following functions (and possibly others) from
'template' be in the 'pretty' package instead?
{{{
pprint :: Ppr a => a -> String
pprint x = render $ to_HPJ_Doc $ ppr x
class Ppr a where
ppr :: a -> Doc
ppr_list :: [a] -> Doc
ppr_list = vcat . map ppr
instance Ppr a => Ppr [a] where
ppr x = ppr_list x
}}}
I guess they can't be moved exactly as they are because the Doc type is
different between the packages, however, I was looking for a class of
"pretty-printable" values and it is strange that the only such class seems
to be Ppr in the 'template' package...
