Nice Page: A Comparative Look at Some Ruby Idioms

Renaud Waldura has a nice page called A Comparative Look at Some Ruby Idioms that compares Java, Perl, and Ruby versions of stuff like

• Constructors & Accessors
• Function Pointers
  
• Exception handling
  
• Iterators
• Variable Argument Lists
  

Useful because for many of us the some Ruby Ways are rather strange if you are coming from another language.
