It does. I was just trying to see what happens if you apply the idea 
consistently. I guess taken to extremes you'd also get

    def f(x,y) then x+y

which I don't particularly like, but then one-line method definitions 
are pretty unusual.

<aside>
I still like that better than "f =-> x,y {x+y}" from 1.9, which is 
horrid

I'd much rather have a new keyword: "f = fn(x,y) {x+y}"

No, not really.

It might be useful for 'if' though. I quite often write code with lots 
of backwards lines:

   something if foo
   raise "Error" unless bar
   other if baz

and it would be good to write them the right way round. (Although 
"unless...then" doesn't really read well either)

More importantly,

   if (x = some_big_calculation) then x.something

can't be written in backwards form currently.
