Represents writing local variables using a regular expression match with named capture groups.
/(?<foo>bar)/ =~ baz ^^^^^^^^^^^^^^^^^^^^
Represents a write to a multi-target expression.
a, b, c = 1, 2, 3 ^^^^^^^^^^^^^^^^^
Represents the use of the ‘^` operator for pinning an expression in a pattern matching expression.
