F# tuples into function parameters

Is there any way to convert tuple into separate parameters and put them to function instead of binding to variables?

Something like

let nice funOf5 tupleOf5 =
    funOf5 (Tuple.toParameters tupleOf5)

instead of

let ugly funOf5 tupleOf5 =
    let (number1, number2, number3, number4, number5) = tupleOf5
    funOf5 number1 number2 number3 number4 number5

Thanks.

One solution, is to use pattern matching in the function definition.

This is inspired by the std lib solution for |||> which is 

let inline (|||>) (x1,x2,x3) f = f x1 x2 x3

then you can have

let inline funof5 (x1,x2,x3,x4,x5) f = f x1 x2 x3 x4 x5
