Re: [Haskell-cafe] How to check object's identity?

Hi,

I tried this in ghci:

...

Prelude> 1:2:[] == 1:2:[] True

Does this mean (:) return the same object on same input,

Also, in functional programming, *every* function returns the same output for the same input. That's part of the definition of function. :-) Luke
