You still haven't said why you need this. Only a rather exotic data structure is likely to have a length greater than maxBound @Int. On Tue, Nov 13, 2018, 10:23 PM Vanessa McHale <vanessa.mchale@iohk.io wrote:
I want more than this, actually. genericLength doesn't work over any Foldable.

You can already get these as Data.List.genericLength and Data.List.genericReplicate
As for changing the prelude ones, this would probably cause a lot of busywork. Where I work we compile with -Werror and -Wtype-defaults, so a lot of places might have to get type annotations. On Tue, Nov 13, 2018 at 5:19 PM Vanessa McHale <vanessa.mchale@iohk.io> wrote:
Would it be possible to generalize replicate and length to have type signatures
replicate :: Integral a => a -> b -> [b]
and
length :: (Integral a, Foldable t) => t b -> a
?
There have been a few instances where such a thing would have been useful to me.
