Re: [Haskell-cafe] Re: does the compiler optimize repeated calls?

Furthermore, doing that optimization (common subexpression elimination) can lead to space leaks. So you should not count on the compiler doing it. Besides, I often find it more readable and less error prone to name a common subexpression; only one place to change when you need to change the call.

So there is no benefits from the "functions have no side-effects" property, performance-wise. Pity. -- -alex http://www.ventonegro.org/
