F # function negation chain

Question

I want to negatively return the return value of a function.

Given this function:

let yes = fun() -> true 

I want to implement no as negation yes

 let no = not yes //doesn't work 

Is there any syntactic sugar in F # to make this possible?

PS I'm not looking for this:

 let no = fun() -> not yes() // boring 

Answer 1

This will work:

 let no = not << yes
