I'm not sure why this works though:
irb(main):001:0> def Meth
irb(main):002:1> puts 'from capitalized method'
irb(main):003:1> end
nil
irb(main):004:0> self::Meth
from capitalized method
nil

or what's going on here:
irb(main):005:0> class C
irb(main):006:1> def Meth
irb(main):007:2> puts 'from C'
irb(main):008:2> end
irb(main):009:1> end
nil
irb(main):010:0> C.Meth
NameError: private method `Meth' called for C:Class
        from (irb):10
irb(main):011:0> C::Meth
NameError: uninitialized constant Meth at C
        from (irb):11
irb(main):012:0> C::Meth()
NameError: private method `Meth' called for C:Class
        from (irb):12
irb(main):013:0> class C
irb(main):014:1> def C.Meth
irb(main):015:2> puts 'from C 2nd attempt'
irb(main):016:2> end
irb(main):017:1> end
nil
irb(main):018:0> C.Meth
from C 2nd attempt
nil

I thought capitalized names became class constants automatically, but is it
different for methods?
