@make anyway I was wrong in my example. Best off forgetting it.

@zoowar thanks! thats super useful in showing why I don't understand it good enough, and a little knowledge can be dangerous. Of course the type signature of sort is not general enough, with it's restriction to Ordered types. How about a working proper example, using reverse .. so
g f l = map f $ reverse l
h f l = reverse $ map f l
have the same output for any f :: a ->b, and l :: [a]
?

@make ok.. wel that was just some Haskell to show that it doesn't matter if we sort a list if integers first then map something on it, or map first, then sort. The paper is about what we can prove about a functions from just knowing their type signature. (I think! )
-
@make though we do make quite heavy going of it sometimes.
-
@make oh! mine too! it's just a side hobby really. And I'm sure you can understand it. It's just about the reason that
`map (*2) $ sort [1,5,4,7,2,5] == sort $ map (*2) [1,5,4,7,2,5]`

@make No! lifes too short! Also the reason it didn't get drunk immediately was we got distracted reading Wadlers paper on "Free Theorems" https://people.mpi-sws.org/~dreyer/tor/papers/wadler.pdf

@zoowar don't have one!

@make I think I will survive. I wanted #coffee about 16:00 but now I will wait until tomorrow. The :-( sad part is... I made the last of it into a cup for a friend, but they did not drink it and let it go cold. GRRRR!!!!

Please kill me now, I just found myself looking at my Twitter Analytics.

@make I went to my fave coffe shop, but they had just closed, They don't open until 10:00 tomorrow. I may have to stand outside in the morning.
-
I have run out of coffee beans. This is *BAD*

@theru Are you on a boat, about to come alongside, strike out and piratically plunder it for its wealth of knowledge?
-
@ana I use L.O calc all the time too. Mostly to read excel spreadsheets other people have made. I want kill the spreadsheet though.
