Error message on use of != should suggest use of /=
Currently when one uses != instead of /= it comes up with this error message
Not in scope: ‘!=’ Perhaps you meant one of these: ‘Map.!’ (imported from Data.Map), ‘>=’ (imported from Prelude), ‘==’ (imported from Prelude)
Considering != is very common for unequal in other languages there should be a more helpful hint to use /= instead of or in addition to the current generic symbol error.
