Primitive types and Prelude shenanigans

[Simon Peyton-Jones]

| Why not just let
| 
|   if x then y else z
| 
| be syntactic sugar for
| 
|   Prelude.ifThenElse x y z

The burden of my original message was that
a) this is reasonable, but
b) it would have to become the *defined behaviour*

As you say, the "defined behaviour" would have to cover
guards as well, and I'm not absolutely certain what else.

The way GHC is set up now, it's relatively easy to make such
changes (this wasn't true before).  But it takes some design work.  

If someone cares enough
to do the design work, and actively wants the result, I'll see how
hard it is to implement.
