class Prism::InterpolatedMatchLastLineNode

表示一个包含插值的正则表达式字面量，该字面量用于条件语句的谓词中，以隐式匹配 IO 对象读取的最后一行。

if /foo #{bar} baz/ then end

=== (other)

Source

# File lib/prism/node.rb, line 10775
def ===(other)
  other.is_a?(InterpolatedMatchLastLineNode) &&
    (flags === other.flags) &&
    (opening_loc.nil? == other.opening_loc.nil?) &&

    parts.zip(other.parts).all? { |left, right| left === right } &&
