This is an experitmental ES.next->ES5 transpiler.

What works:

• the <| operator -- defines the [[Prototype]] of a literal (uses __proto__)
• the .{ operator -- extends the LHS object with properties from an object literal
• object literal property shorthand -- {x, y} -> {x: x, y: y}

What sort of works:

• let and const declarations: no block scope for let
• super propertry references: no early syntax errors
