def ==(other)
  self.class === other and to_a == other.to_a
end

#===(other) ⇒ Object

Does other match this platform? Two platforms match if they have the same CPU, or either has a CPU of ‘universal’, they have the same OS, and they have the same version, or either has no version.

#=~(other) ⇒ Object

Does other match this platform? If other is a String it will be converted to a Gem::Platform first. See #=== for matching rules.
