About method naming convention with "!"
in [Ruby]

From: Paul A. on 27 Jun 2010 17:29 Hi, Is there a reason why Array#clear method have not a exclamation mark (!) at the end? Just like Array#map! because the object is altered (so it's called a dangerous method). In my opinion, Array#clear is an as dangerous one that alters its object, and it may be used with the exclamation mark... What do you think about? Thanks for your comments. -- Posted via http://www.ruby-forum.com/.

The ! only has meaning when there's also a non-! method of the same name. There's no general or abstract notion of danger -- it's always comparative.
