Using && or and in Ruby

Two reasons why I use && in my code:

• The Rails source does
• I learned to program in C++ so the following is downright scary

a = 'test'
b = nil
both = a && b       # both == nil
both = a and b      # both == 'test'
both = (a and b)    # both == nil

One reason why using and is better:

• It reads well

You will get bitten very hard (I have more times than I care to recall) if you don’t pay close attention to which one you’re using, so I prefer using && everywhere now.
