Hello
people,
I've been studying
the Haskell 98 report as part of my study of the Haskell language and need to
rant just a little bit.
<micro-rant>
As long as were
trying to clean up a final version of the Haskell 98 report, lets simplify it a
little by getting rid of unary minus.
It's the only prefix
operator in the whole language.
It requires messing
up the otherwise clean expression syntax.
It has a meaning
that the user can't change, very rare in Haskell.
It even has a fixed
precedence level.
It leads to
excessive confusion when dealing with sections involving '-' (the binary
operator).
Uses can be replaced
by either negate x or 0-x.
</micro-rant>
I know we can't
actually remove unary minus at this point, I just had to get this off my
chest.
