Posts in the “haskell” category

There may be other ways to do this, but if you need to determine the type (type signature) of an object in a Haskell program, the following approach worked for me.

First, add this import statement to your program:

import Data.Typeable

What that does is give you access to a function named typeOf, which you can then use like this:

“I use Haskell because I want to be able to refactor without fear, because I want maintenance to be something I don’t resent.”

This is another quote from the book, Haskell Programming from First Principles. I guess you could say that I use Scala for similar reasons.
