Future work

• Functions (e.g. min, strlen, select, slice, dec, asize)
• Dynamic label definition to/from string (.define "name", 12, lbl("name"))
• Better tests (error cases, CLI arguments)
• Restructuring files and imports
• Allow running easier
• API for use in other node-apps?
• More directives? (e.g. while loops?)
• Anonymous labels? (:, can be referred to with :+[+...], :-[-...])
• Custom functions? (.function myFunc 2 \1*\2, %myFunc(3, 4))
