TryHaskell uses http://hackage.haskell.org/package/mueval http://hackage.haskell.org/package/mueval and not ghci
You can eval expression so following works
let t ="foo" in t
- nandemo 14y agoYeah, I saw that it uses mueval, but it's still conceivable that TryHaskell itself could hack support for let on top of it. Apparently Chris planned to do it [1]. Note that in "let t=bar in foo" the scope of t is restricted to foo, so the example above still doesn't work.

- jonke 14y agoFair enough but you could do let f = map reverse in f ["ab", "cd"] IMHO the tryhaskell expose more or less only simple pure functions and I doubt that anyone with a real interest in haskell will get any substantial out of it. However if one is completely new to programming maybe TryHaskell and these 6 short lessons have a value.
- nandemo 14y agoAgreed. Incidentally, Chris Doner has been producing far more exciting things like Fay, so I'm not gonna complain about TryHaskell.
