Subject: Warnings on assignments in conditionals?

I consider the following statements to be perfectly legit (although 
perhaps slightly ambigious) and Ruby does obey, but throws this 
mandating warning. Am I just being paranoid or is Ruby forcing a style 
upon me :)?

irb(main):008:0> if a = 1 then true else false end
(irb):8: warning: found = in conditional, should be ==
=> true
irb(main):009:0> a
=> 1

irb(main):010:0> if a = nil then true else false end
(irb):10: warning: found = in conditional, should be ==
=> false
irb(main):011:0> a
=> nil
