* Fix Trac #2766: printing operator type variables
}}}
Now we get
{{{
Prelude Control.Arrow> :t first :: Arrow (~>) => b~>c -> (b, d)~>(c, d)
first :: Arrow (~>) => b~>c -> (b, d)~>(c, d)
:: (Arrow (~>)) => (~>) b c -> (~>) (b, d) (c, d)
}}}
It's be better still to print the operator infix, but the pretty-printer
for `Type` does not know about fixities, so I have not done that (yet,
anyway). But at least it's a legal type now.
