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.
