:: Brilliant. No need for another task. --[[User:Paddy3118|Paddy3118]] 19:18, 14 June 2012 (UTC)
:: Agreed. Although it is less elegant than composing multiple functions with a single call, it does demonstrate that a language supports function composition without having to resort to additional functional programming language features. I would still prefer to see the task defined more precisely because I'm afraid we'll end up with several (sin (asin (sin x))) implementations. I haven't come up with a good example (yet), but I think that changing the task description to include the following output should separate most of the wheat from the chaff. --[[User:Lhignight|Larry Hignight]] 23:00, 20 June 2012 (UTC)
