I'm not sure that raising SyntaxError counts as a valid entirely different
meaning <wink>.  Seriously, that has no meaning now.

     if x and y else z
     :if x and y else z
     if x: and y else z
     if x and: y else z
     if x and y: else z
     if x and y else: z
     if x and y else z:

are all SyntaxErrors now.  Presumably only the last would grow a meaning
under Holger's suggestion.

Using a conditional as an if's test expression is likely unreadable no
matter how it's spelled, though.  I really can't make head or tail out of

    if if x: y else: z:

at first (or second, or third) glance either.
