A quotation from Wikipedia, the free encyclopedia:Some programming

languages have built-in syntactic support for currying, where what looks like a

multi-argument function is actually syntactic sugar for the function in curried

form; notable examples are ML and Haskell, where in both cases all functions

have exactly one argument.
Is this also valid for F# ??? I mean have all function definitions in F# a curried form by default?
Thanks.

.

Well yes:

A -> B -> C

stands for a function taking a A and returning a function that takes an B and returns a C

If you type something like fun a b -> blabla you get this, if you type fun (a,b) -> you get an function taking a TUPEL (a,b) for input so if the return type is C you get (A,B) -> C

BTW: F# is "based" on OCAML and this is a descendant of ML

But of course all this stuff gets translatet into IL and there you get something very diffent ... but you should only care for this stuff if you are planning to use F#, C#/VB etc. side by side.
