* range.c (range_step): iteration done using "+" if elements are
Numeric. Otherwise using "succ". * range.c (range_each): iteration done using "succ". If the elements does not respond to "succ", raise TypeError. As a result, all Enumerable methods, e.g. collect, require elements to respond to "succ'. * range.c (range_member): comparison done using "each", if elements are non-Numeric or no-"succ" objects. Otherwise compare using "<=>". * range.c (Init_Range): remove "size" and "length". git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@2506 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
