02:54 AM Ruby Bug #21558 (Feedback): Regexp.union with multiple regexps returns a non-shareable object (should be shareable if possible)

Regexp.union returns a non-shareable object when given multiple Regex arguments. Is this expected behavior?
It would be preferable if the resulting Regexp were shareable, since single-argument `Regexp.union` does produce a shareable obj... niku (niku _)

02:37 PM Ruby Feature #6528 (Closed): Add Pathname#write and Pathname#binwrite

IO.read と対応する Pathname#read があるので
IO.write と対応する Pathname#write が欲しいです．
