  New Revision: 52435

  http://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=52435

  Log:
    include/ruby/ruby.h (struct RObject): hide iv_index_tbl type
    
    This is an implementation detail and should not be exposed to
    C extension users.  We may change this to id_table soon; and
    id_table should not be exposed as a public API.
    
    It is highly unlikely any existing C extensions require this;
    so the risk of breakage is very low.  Ideally, all of RObject
    could be hidden.
    
    [ruby-core:71306] [Feature #11647]
