Tuple construction already has a "no comma, no tuple" problem.  That 
problem remains, but as soon as you add a comma, you'll get the same 
protection as you get for lists.

Having read and written tons of existing code, I'm not so sure about 
that.  A tool that wraps backslash-escaped blocks in parentheses would 
take care of most cases.  What's left after that is probably ambiguous 
to a human reader anyway.
