For those unfamiliar with Elixir, the most interesting aspect might be how it achieves this. `es6_maps` takes advantage of BEAM (Erlang's VM) hot-reload capabilities to amend the Elixir compiler bytecode at runtime, adding functions that expand the shorthand syntax for further compilation. I think it's a nice showcase of the power you can wield (with care) when…
