Record expressions

A record expression constructs a record from a sequence of key/value pairs. If all key/value pairs are atomic, then the record itself is also atomic.

An empty record has the following syntax:

[->]

A record with pairs in it has the following syntax:

[
  some-key -> Some-expression,
  "some other key" -> Some-other-expression,
  (Key-expression) -> Another-expression,
]

The sequence of pairs can have a trailing comma, but it’s not required.
