Bug #6029: Should OpenStruct implement #eql? and #hash?

• Status: Closed

[marcandre (Marc-Andre Lafortune)]

Currently, OpenStruct have no specialized #eql? and #hash, so:

require 'ostruct'
x = OpenStruct.new(foo: 42)
y = x.dup
x == y    # => true
x.eql?(y) # => false

This means that OpenStruct does not behave like Struct, Array, Hash and other structures by comparing its fields and values.

This also prevents using OpenStructs as hash keys (unless one uses the exact same object as the key), contrary to other structures.

Is there an historical reason for this?

How likely would it be that adding #eql? and #hash create conflict with some fields?
