The same thing happens in 1.9 mode. methods, private_methods, and protected_methods work fine.

Regarding the spec question posed in IRC, it means the spec should go in spec/ruby/core/kernel/public_methods_spec.rb, since that's where behavior of this method is described.

Please use other wording than it "works", since that doesn't really convey any meaning. Probably something like it "returns public methods for immediates", since that describes what it does.

@rf- rf- Add failing spec for Fixnum#public_methods 1b8df69
@rf- rf- Override public_singleton_methods in ImmediateValue
This fixes an issue where calling public_methods on a Fixnum would call
Kernel#public_singleton_methods and raise a TypeError.
