Operator functions

[Jomy10]

Operator functions will be declared in one of these ways (still to be decided):

op func (lhs: i32)++ {}
// or
op (lhs: i32)++ {}
// or
oper (lhs: i32)++ {}

Operator functions are special functions, they allow you to do things like the following:

op (lhs: i32) $ (rhs: i32) -> i32 {
    return lhs * rhs / lhs
}

let val = 4 $ 5
// val = 5

op ++(rhs: &i32) -> i32 {
    rhs += 1
}

let val = 5
++val
// val = 6

op (lhs: i32) |> (rhs: func(i32) -> i32)) -> i32 {
    rhs(lhs)
}

func one(i: i32) -> i32 {
    return i + 1
}

func two(i: i32) -> i32 {
    return i + 5
}

let val = one(4) |> two
// val = 10

Not sure

• if op (lhs: i32)++ will be the same as (lhs: i32) ++ (variable++ vs variable ++)
• if it will be allowed at all to have variable++ instead of variable ++
