While porting some C# to F# recently I got sick of rewriting ternary operators like this

var result = condition ? "True Branch" : "False Branch";

into a form like this

let result = if condition then "True Branch" else "False Branch"

or

let result = match condition with true -> "True Branch" | false -> "False Branch"

Thankfully, although F# lacks an inbuilt ternary operator it does allow you to define your own operators

/// Custom ternary operator
let (?) truth trueBranch falseBranch =
    if truth then trueBranch else falseBranch
    
let test condition =
    (?)
        condition
        "True branch"
        "False branch"
