Hello,
I stumbled upon the following problem:

irb(main):001:0> guy = "Bob"
=> "Bob"
irb(main):002:0> guy.define_singleton_method(:hello) { "#{self}: Hello there!" }
=> :hello
irb(main):003:0> guy.hello
NoMethodError: private method `hello' called for "Bob":String
from (irb):3

This is probably related to #9005.

proc.c: make method by define_method public

• proc.c (rb_mod_define_method): consider visibility only if self
  in the caller is same as the receiver, otherwise make public as
  well as old behavior. [ruby-core:57747] [Bug #9005]
  [ruby-core:58497] [Bug #9141]
• vm.c (rb_vm_cref_in_context): return ruby level cref if self is
  same.
