Unary minus (was: micro-rant)

[Simon Peyton-Jones]

Folks

I suggest we transfer this discussion about unary minus to
haskell-cafe@haskell.org.

As the original poster noted, it is not a subject on which the existing
Haskell report=20
is ambiguous or inconsistent, so I don't propose to make any change in
Haskell 98.
The next version of Haskell, maybe.

Simon
