Hi Ruby Core,

I noticed that Module#constants(false) sometimes includes modules/classes with a lowercase name:

Complex.constants # => [:I]
Complex.constants(false) # => [:compatible, :I]
Complex.const_defined? :compatible # NameError: wrong constant name compatible

NameError.constants # => []
NameError.constants(false) # => [:message]

Also:

• Rational --> compatible
• IO --> generic_readable
• IO --> generic_writable
