Interesting.

Also:

	>>> print 1; print 2; if [1]: print 3
	  File "<stdin>", line 1
	    print 1; print 2; if [1]: print 3
        	               ^
	SyntaxError: invalid syntax


I haven't looked at the actual grammar in quite a while, but I'm
guessing that there is a bit of an overgeneralization in the rules
to prevent compound statements like: 

	>>> for x in [1,0,2]: if x : print x 
	  File "<stdin>", line 1
	    for x in [1,0,2]: if x : print x
                       ^
	SyntaxError: invalid syntax


which are definitely disallowed.
