[Haskell-beginners] find problem

[Roelof Wobben]

Hello, 

Sorry for asking so much but I really want to understand this.

I have the function find  k t [v, (k',v') <- t,k = v]

Let's say k = false and t = [false, true, false, true]

Then It will be  find  "false" ["false", "true", "false", "true]
But where on earth are t,k = v and (k', v') come from ?
