Target version changed from 2.0.0 to next minor I am sorry but it's too late. I admit my fault. Matz. ---------------------------------------- Feature #6083: Hide a Bignum definition https://bugs.ruby-lang.org/issues/6083#change-32030 Author: ko1 (Koichi Sasada) Status: Assigned Priority: Normal Assignee: matz (Yukihiro Matsumoto) Category: Target version: next minor Now, the struct RBignum which is a definition of Bignum in C is located in include/ruby/ruby.h. It means we can't change implementation of Bignum. For example, using GMP as Bignum representation. I propose to move the struct RBignum definition from include/ruby/ruby.h to bignum.c. I believe no one use struct RBignum directly (except core). It has possibility to break binary compatibility. -- http://bugs.ruby-lang.org/
