"can" != "should".

The transforms *can* be represented in the current 
syntax, but we agree that the current idiom should 
be improved.  Different changes may be preferable 
for other patterns.

Depends on the newbie, and the definition of "language lawyer".

Most programmers want a manual or reference when they're first
learning, and will turn to it when they get confused.  (Hey, 
I got a syntax error!  What's up?  Hey, this function just 
changed its signature!)  Then they'll see the full syntax.

There will always be more newbies -- even a year after this
enters the language.
