This is the full (admittedly still a bit of a work-in-progress PR) that integrates #1886 into main.

Some quick comments but there's more, I just need to eat lunch.

This is coming along very well! I'll try to consolidate my thoughts in this PR 🙂

Need to filter on symboltype when searching symbols. Function name and and class name match, Go to definition on [type] shows constructors etc. Related comment Integrating class symbol support fflaten/PowerShellEditorServices#16 (comment)
- Note: Example below will need special handling like type vs class/enum for EnumMember definition vs Property reference (or replace EnumMember with Property for simplicity).
Consider matching [classname]::new() with classname() constructors? Same as Integrating class symbol support fflaten/PowerShellEditorServices#16 (comment)
Missing method overload in outline and workspace symbol search
Hide variable symbols in outline+workspace for method parameters in definitions (image above)
Remove variable symbols for parameters in function/cmdlet calls
Only show variable assignment symbols for top-level assignments like stable? To remove noise in outline and workspace symbols - at least until we're able to handle scopes better. Related discussion Integrating class symbol support fflaten/PowerShellEditorServices#16 (comment)
- Also for go to definition? Will currently list reassignment inside of out-of-scope functions
Outline, workspace symbol search and go to definition jumps to function-keyword and not name (using scriptrange atm?).
Currently undoes fix for Outline, symbol search and go to definition should jump to symbol name #1905 in original PR.
Struggles with large files. Outline, workspace symbols and hover works. Codelens shows "no command", go to definition doesn't work, highlight on click etc. (anything searching for specific symbol?) fails. Try Pester.psm1 (17k lines).
Update 24/1: Fixed in latest commits 🎉
New 24/1: Hovering a function name should only highlight the name. Currently highlights full definition and full invocation/call

This PR would also fix #1889 and #1904 🎉

Latest commit fixed the reference-issue with large files 🎉 I've updated the previous post

Since `FindReferencesOfSymbol` is already used.

This required using a `ScriptFile` for the associated test in `AstOperationsTests`. The coupling of the visitor to the file seems fine since that's the _point_ of this improvement: a cached sets of references for each file. We also have to carefully sort our list of symbol references for things that expect them in order.

            {
                Label = parameterInfo.Name,
-                Documentation = string.Empty
+                Documentation = parameterInfo.HelpMessage


Patrick Meinecke (@SeeminglyScience) Not a whole lot comes from this it seems.

So that we rely on the dictionary to sort our symbols into the equivalent types instead of having to perform a filter.

I think there's a cleaner way to do this, but this works.

Against the full name and not just the identifier, since it's what's displayed in the search menu. Now you can search methods by their parameters' names.

Should have been just `IndexOf`, and also use `+` instead of `string.Concat()` for simplicity and speed.
