[MLton] should Date.{fromString,scan} allow space instead of zero?

[Henry Cejtin]

I love the notion of a wrapper around the official basis.  The only argument
against it (and I think this isn't a trivial one) is that it means when you
see code like
	... Int.toString ...
the semantics are NOT going to be what one would expect from the standard
basis spec.
I don't know what to do about that.  At the moment my code does things like
	Fixed.Int.toString
just to make it clear in ths source what is going on.  Not a great solution.
