In Ruby, there are nine different conditionals. All of them are 
technically expressions, because Ruby makes almost nothing of a potential 
difference between expressions and statements.

statements are a redundant concept and are vestigial from jurassic PASCAL.
(and C, of course, but it didn't rhyme)

the reverse "if" in Ruby is more of a mirror image of "and" than it is of 
the forward "if". It's just like it is in Perl.
