Automatic Semicolon Insertion

[trimorphdev]

The language should have automatic semicolon insertion, similar to that of Go's.

let my_variable = 0   // can end here, insert semicolon
let my_variable = 1 + // can't end here, don't insert semicolon
    2                 // can end here, insert semicolon

Automatic semicolon insertion occurs during lexing/tokenizing.
