Re: [Haskell-cafe] Tracking down where an instance comes from

I can support the guess. A similar problem was found in Tasty a while ago: https://github.com/feuerbach/tasty/issues/71 In the case of Tasty, the problem was solved by using regex-tdfa-rc instead of regex-tdfa. On Tue, Oct 28, 2014 at 11:58:23AM +0100, Tobias Florek wrote:

Hi,

instance [safe] Show (a -> b) -- Defined in ‘Text.Show.Functions’

What would be the best way to track down through which import this actually comes in?

I might be late and you already found it, but my strong guess is that it's regex-tdfa.
