=== (other)

Source

# File lib/prism/node.rb, line 17564
def ===(other)
  other.is_a?(SymbolNode) &&
    (flags === other.flags) &&
    (opening_loc.nil? == other.opening_loc.nil?) &&
    (value_loc.nil? == other.value_loc.nil?) &&
    (closing_loc.nil? == other.closing_loc.nil?) &&
    (unescaped === other.unescaped)
end

实现节点的相等性判断。这实际上是 ==，但不比较 location 的值。仅检查 location 是否存在。
