Hi,

I test some simple F# code for "if" expression, but the result is unexpected for me:

> let test c a b = if c then a else b;;
val test : bool -> 'a -> 'a -> 'a

However

> test true (printfn "a") (printfn "b");;
a
b
val it : unit = ()

I'd expect only "a" is printed out but here I got both "a" and "b". I wonder why it comes out this way? Thanks!
