Answer 1

The Ruby community has put an incredible amount of attention to automating this idiom. These are the solutions I know of:

• try in Ruby on Rails
• Another try
• andand
• A safer andand
• Kernel::ergo
• send-with-default
• maybe
• _?
• if-not-nil
• turtles!
• method_ in Groovy style
• do-or-do-not

The most well-known is probably the try method in Rails. However, it has received some criticism.

In any case, I think Ben's solution is perfectly sufficient.
