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.

Hi
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.
Thanks
