Prune import statement symbols

[sir4ur0n]

It's been a long time since my last issue 😛

Currently HLS considers each import statement as a symbol, which has several minor inconveniences, e.g.:

• Go to symbol is spammed with import statements, which - I think - almost nobody will ever use
• Go to Next Member stops at each import statement, while the whole point is to quickly navigate in the file

I just checked how it's done e.g. with Java files: import statements are not even symbols.

Concrete example:

module Foo where

import Prelude
import Data.Text
import GHC.Generics
import GHC.Arr

foo :: ()
foo = ()

bar :: ()
bar = ()

data Foo

newtype Bar = Bar Foo

class Baz a

instance Baz Foo

As you can see, there is a symbol for the module declaration, another for "the group of imports" (which I find awesome), in my opinion there is no benefit to also consider each import statement as a symbol.

What do you think?

Is it possible without breaking the highlighting an appropriate import statement when a caret is on the symbol's usage?
