See the attached script for an example. The #bla method should always be defined on the metaclass of "klass". See https://bugs.ruby-lang.org/issues/11360#note-2 as well in which I warned against this problem ;) ---Files-------------------------------- objspace_expose_intern_meta.rb (413 Bytes) -- https://bugs.ruby-lang.org/
