Represents a hash key/value pair.
{ a => b }
^^^^^^
The key of the association. This can be any [non-void expression](github.com/ruby/prism/blob/main/docs/parsing_rules.md#non-void-expression).
{ a: b }
^
{ foo => bar }
^^^
{ def a; end => 1 }
^^^^^^^^^^
The value of the association, if present. This can be any [non-void expression](github.com/ruby/prism/blob/main/docs/parsing_rules.md#non-void-expression).
{ foo => bar }
^^^
{ x: 1 }

Implements case-equality for the node. This is effectively == but without comparing the value of locations. Locations are checked only for presence.
