Bug #8043: Marshal will dump some object with singleton methods
https://bugs.ruby-lang.org/issues/8043

Author: marcandre (Marc-Andre Lafortune)
Status: Open
Priority: Normal

Category: core
Target version: current: 2.1.0
ruby -v: r39608


The check for "dumpability" is incorrect:

    o = Object.new
    def o.foo; end
    Marshal.dump(o) # => TypeError: singleton can't be dumped
    o.singleton_class.send :prepend, Enumerable
    Marshal.dump(o) # => "\x04\be:\x0FEnumerablee:\vObjecto;\x06\0", should fail
