Concurrent Clean uses the ~ symbol for unary negation. That's also a way of fixing it. Personally I could also live with allowing no space between the minus sign and the number... If you leave a space, - becomes the subtract operator. Coming from C++ I always make the mistake to forget parentheses around negative numbers in Haskell, which is very often needed.

I think you should have to write negative numbers using the syntax 0-10, since currently having one single unary operator is ugly.
I think writing 0-10 is ugly.
Ugly - yes. But very clear as to its meaning. How often do people actually write negative numeric literals? My guess is that -1 is the most common by a long way, but even that is quite rare. Of course, real statistics of real programs are the only answer.
