Expand description

The external, unpacked, enumeration representation of a scheme value.

Values that are not potentially cyclical, such as syntax objects and byte vectors use Arcs as they are much less expensive than Gc types.

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
