v5 Modules

Motivation

• organize code
• control visibility
• make linking explicit

Syntax

module math { export fn add(a,b){ return a+b; } }
module main { import math; let x = math.add(1,2); }

Rules

• export only fn/vars
• qualified access with .
• main is last
• imports must refer to earlier modules

Runtime idea

• module -> map of exports
• map stored as global const
• math.add -> math["add"]
