x/tools/gopls: Inlay Hint: show name of a long function at its final brace

[spcxtesla]

gopls is excellent. Thank you. It would be even better if it could add another feature.

func foo() {
} // foo

An example is shown above where we could add "// foo" to the end of function definition. This is helpful to identify the end of a long function. Also, the idea applies to struct/if/for definition as well

Hi @spcxtesla, thanks for raising this, I think a similar solution like inlay hint might be better.

However, I think the client may already have certain feature available using the folding range. Like vscode stick scroll feature:

    "editor.stickyScroll.enabled": true,
    "editor.stickyScroll.defaultModel": "foldingProviderModel",

this is built on top of the foldingRange provided by the gopls or indentation. When the cursor is next to the closing }, the column will be highlighted and you will be able to see which line (which statement) is introducing this folding range.

Seems reasonable; users can pick and choose which inlay hints they see, and it's cheap to compute. Send us a CL.
