Re: [Haskell-cafe] Ralf Laemmel's riddle on surviving without the monad transformation library

I haven't watched the lecture. But what does he mean "survive"? Does it mean to do anything that you can do with mtl? On Mon, Nov 15, 2010 at 12:53 AM, C K Kashyap wrote:

Hi,

Can someone provide me the solution to the following riddle that Ralf asked in his lecture at http://channel9.msdn.com/Shows/Going+Deep/C9-Lectures-Dr-Ralf-Lmmel-Advanced...

Riddle: define a custom made monad (only involving (->) and Either String) to survive without the monad transformation library.
