That is a very good point. Canonicalizing to an unbounded range doesn't work,
because, as it stands, the ranges '[1, INT_MAX]' and '[1,)' are *not* equal. So
the only remaining option is to canonicalize to the closed form always.
I still think we should strive for consistency here, so let's also make
'[]' the default flags for the range constructors.
