Please VOTE! Changing keywords to functions

We have already changed "print" and "yield" from keywords to functions.
Guido specifically mentioned "exec" so I will put that on my to-do list to
change also.

Greg's logic for changing "print" was that "there was no reason for it to be
a keyword".  Martin pointed out that functions can be overriden while
keywords cannot.

Both of these arguments can be applied to any keyword that doesn't include a
code block with maybe these exceptions...

The keyword "del" has a syntax problem if changed to a function.  It's args
would be evaluated instead of kept as l-values.

The keyword "pass" should stay special since it generate no code.

The three keywords: "break", "continue", and "return" have no reason to be
treated special except that they are already keywords in a zillion different
languages. Yield is now a function so why not return?  It is really nice to
be able to say break and continue without following it with parens though.
The parser does treat return a bit special right now so if it wasn't a
keyword I may get into trouble, but this could probably be fixed.

That pretty much leaves this list as candidates for conversion...

	assert    
	from                  
	import             
	raise  
 
Please vote on which keywords you think should be changed to functions.  

I vote for adding exec, assert, from, import, and raise in addition to print
and yield.
