Subject: Re: Method Chaining Issues

This is a FAQ, though no page on the RubyGarden wiki seems to address
it.

Some kind soul should search the archives for all the threads and RCRs
surrounding this topic and create a page on the wiki with links, so we
can redirect people to it.

In short - some people think it's nice that the 'bang' methods return
nil if no change was effected, some people do not. You can either chain
them using intermediary strings:

  string.sub('old','new').reverse

or you can use the bang methods, but not use chaining

  string.sub!('old','new')
  string.reverse!
