class Prism::InstanceVariableWriteNode
Represents writing to an instance variable.
@foo = 1 ^^^^^^^^
Attributes
The name of the instance variable, which is a ‘@` followed by an [identifier](github.com/ruby/prism/blob/main/docs/parsing_rules.md#identifiers).
@x = :y # name `:@x` @_foo = "bar" # name `@_foo`
The value to write to the instance variable. It can be any [non-void expression](github.com/ruby/prism/blob/main/docs/parsing_rules.md#non-void-expression).
@foo = :bar ^^^^ @_x = 1234 ^^^^

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