Idea: suggestion for missing "with Ada.Strings.Fixed" and "Ada.Characters.Handling"

[zertovitch]

When you write a "Put_Line" without a "with Ada.Text_IO;", GNAT suggests, and GNAT provides the "wrench" for it, to add "with Ada.Text_IO; use with Ada.Text_IO;". It is super useful.
In a similar way, I have more than often, since decades, the case where "To_Lower", "To_Upper" or "Trim" are not known to GNAT.
It would be extremely cool to have a similar suggestion with an auto-fix with
"with Ada.Characters.Handling; use Ada.Characters.Handling;"
and
"with Ada.Strings.Fixed; use Ada.Strings, Ada.Strings.Fixed;"
depending on those function names (and perhaps others).
Especially, "Ada.Characters.Handling" is not an obvious place to search for "To_Lower" and "To_Upper", so it would be welcoming for beginners.

Hello,

We are working on LSP codeActions in the Ada Language Server side for that. We will also provide a way to irectly import missing packages when using completion to import an invisible symbol: that would solve your issue.

Keeping you posted.
