Style/DoubleNegation allowed_in_returns doesn't take into account define_method and define_singleton_method

[dorianmariecom]

---

Expected behavior

The default rubocop configuration shouldn't return errors when using !! in the return of a define_method/define_singleton_method

Actual behavior

rubocop reports an error:

a.rb:2:3: C: [Correctable] Style/DoubleNegation: Avoid the use of double negation (!!).
  !!good
  ^
a.rb:6:3: C: [Correctable] Style/DoubleNegation: Avoid the use of double negation (!!).
  !!bad
  ^

Steps to reproduce the problem

define_method :good? do
  !!good
end

define_singleton_method :bad? do
  !!bad
end
