If you search Google, you will likely find some huge comparason of if
or flow control statements in general, in zillions of languages.

I personally like

if expr [then | { | do | :]
  the code
[done | } | ]

As long as it starts with if and is immediately followed by expr, I
could care less about the rest, unless someone forgets to document
it ;-). Lisps cond is also sexy.
