Subject: Syntax error I don't understand

(I'm using Ruby 1.8.6.)

I'm trying to add a random number to an array. I do:

  a = []
  a << rand 3

But ruby replies with "syntax error, unexpected tINTEGER, expecting kDO
or '{' or '('"

Why's that?

When I add parentheses to the function call, as in...

  a = []
  a << rand(3)

...then I don't get this syntax error. I'd like to understand why this
happens.
