问题
While playing with Erlang getting started section I have met bizarre syntax error on trivial use case (simple map initialization). Are there any suggestion why does that happen?
1>
#{ "key" => 42}.
- 1: syntax error before: '{'
Details: Erlang R16B03 (erts-5.10.4), Eshell V5.10.4.

Because maps were introduced in Erlang 17.
You have to upgrade your installation or do not use maps.
