But now consider:

	t = a, b > c, d

This _is_ legal, and refers to a 3-tuple.  It's legal in an if clause,
although the parentheses are required.  What you want is an exception so
that the _same exact code_ will have different meanings in different
contexts (in one case it creates a 3-tuple, in the other it does a
pairwise comparison of two n-tuples).  This is an extremely bad idea.
