Feature #17099: Remove boolean argument and warning from Module#attr - Ruby master - Ruby Issue Tracking System

Feature #17099

Updated by S_H_ (Shun Hiraoka) over 4 years ago

`Module#attr` works as `Module#attr_reader` by default(since in `1.9.1`). 
 And, optional boolean argument is obsoleted(But, it works as `Module#attr_writer` given optional argument `true`). 

 I think it's okey to remove `Module#attr` warning (with given optional boolean argument).
