The return statement is causing an early break.
it doesn't do what you think it does (what it does in other languages)
The desired behavior is in q2.
Ruby automatically returns the result of the last statement in the  
block.
Also, a clue that you're thinking in another language is the curly  
braces.
Ruby style is to use curly braces for one-liners and do-end for multi- 
line blocks.
