Issue #1732 has been updated by Run Paint Run Run. > It's because Enumerable#to_a doesn't transfer its taintness and > trustworthiness. Should it do? I assumed it would, because Array#to_a/#join does. But I don't pretend to be a language designer. ;-) matz, I'm sorry to be annoying, but I don't understand this revision.

Could you clarify? :-) ---------------------------------------- http://redmine.ruby-lang.org/issues/show/1732 ---------------------------------------- http://redmine.ruby-lang.org
