Comments

Mint supports inline comments (single line): // ...

Multiline comments have the following syntax: /* ... */

// Set a variable.
let name =
  "Joe"

/*
   Convert it to upper case.
   => JOE
 */
String.toUpperCase(name)

Mint doesn't have a tokenizer so if there is a place where you would like to use a comment but can't, open an issue!
