# Comments

Comments can be written using `//`

. For instance:

`// The following computes the factorial of a number.`

let

rec fact(v: int): int = if (v <= 1) then 1 else v * fact(v - 1)

in

fact(4)

Multi-line comments are not supported and must be written with each line containing `//`

as in:

`// The following computes`

// the factorial of a number.

let

rec fact(v: int): int = if (v <= 1) then 1 else v * fact(v - 1)

in

fact(4)
