Hi
Hi. Sorry, I should have put the question differently -- is there sometimes a need to escape hoogle input (i.e. so I could confirm there were no results, rather than getting an error)?
The only one I'm aware of is that searching for any operator such as (+) needs to be done without brackets.
But, thinking about it, there's no reason that this shouldn't give an error as it isn't a type sig. (I was looking for source online somewhere of the monad instance for (->) and only entered it in hoogle out of curiosity...)
If any syntax did work for this, I'd have expected it to be something like "instance Monad (->)". Unfortunately that won't work, and I'm not sure I even can make it work in future versions, since Hoogle is unable to tell where an instance is defined - Haddock abstracts away this information. Thanks Neil
