Re: [Haskell-cafe] Referring to Prelude.(++)

Did you try (Prelude.++)? I think that's the way it needs to be done. Dan On Thu, Sep 24, 2009 at 8:59 PM, Terry Hayes wrote:

I'd like to redefine (++) so that it works on a more general class of "lists" (ListOf a).  To do this, I found that I can import the Prelude hiding the definition of (++).  Then I want to make [] an instance of ListOf, and have the (++) function call the built-in Prelude.(++).

My problem is that I can't figure out how to call the built-in function. Just using "Prelude.(++)" doesn't seem to work in the way that "Prelude.foldl" would (for example).

Any ideas?
