False positive "Unused LANGUAGE pragma"

[cblp]

{-# LANGUAGE QuasiQuotes #-}
[qq|
  ...
|]

gives

example.hs:1:1-28: Warning: Unused LANGUAGE pragma
Found:
  {-# LANGUAGE QuasiQuotes #-}
Perhaps you should remove it.

But without the pragma

[qq|
  ...
|]

TypicalUsage.hs:2:3-5: Error: Parse error: on input `...'
Found:
    [qq|
  >   ...
      |]

$ hlint --version
HLint v3.10, (C) Neil Mitchell 2006-2025

[cblp]

With master version, the same, and also

example.hs:1:1-28: Warning: Avoid restricted extensions
Found:
  {-# LANGUAGE QuasiQuotes #-}
Note: may break the code

Why is it restricted? What does it mean? I cant find anything about it in GHC docs.

[cblp]

okay, found

badExtensions =
  ...
  , QuasiQuotes -- breaks [x| ...], making whitespace free list comps break

Okay, but Hlint breaks [x| ... |], and I always put a space when I type a list comprehension. So what do you recommend instead of QQ to get the result?
