Comment(by lsansonetti@…):

 {{{
     def run_once(default)
       caller_method = Kernel.caller(1).first[/`([^'?!]+)[?!]?'/, 1]
       sentinel      = "@_#{caller_method}_sentinel"
       return instance_variable_get(sentinel) if
 instance_variable_defined?(sentinel)
 }}}

 I suspect that here #caller returns selectors with the trailing ':'
 character.
