FIELDS / TYPEDFIELDS fail on const fields of mutable struct

[i9e1]

Since v"1.8.0" its possible to annotate a mutable struct's field with the const keyword.

If you do, DocStringExtensions FIELDS, TYPEDFIELDS fail: docstrings are only parsed for mutable fields.
Here is a MWE tested with julia v"1.9.2" and DocStringExtenions v"0.9.3".

julia> """Minimal Working Example to demonstrate `const` keyword on mutable struct with fields $(FIELDS) and typed $(TYPEDFIELDS)"""
       mutable struct MWE
           "This is not shown"
           const a::Real
           "This works as it should"
           b::Real
       end;

  Minimal Working Example to demonstrate const keyword on mutable struct with fields

    •  a

    •  b: This works as it should

  and typed

    •  a::Real

    •  b::Real: This works as it should

This is an upstream issue from what I can tell:

julia> """Minimal Working Example to demonstrate `const` keyword on mutable struct with fields"""
              mutable struct MWE
                  "This is not shown"
                  const a::Real
                  "This works as it should"
                  b::Real
              end;

help?> MWE.a
  MWE has fields a, and b.

help?> MWE.b
  This works as it should

MWE.a should give the attached docs, just like MWE.b does. It doesn't. We can't fix anything in DocStringExtensions.jl until that issue is fixed.

Has an issue been opened on https://github.com/JuliaLang/julia/issues regarding this, that I can track?

[MichaelHatherly]

@i9e1 did you open one?

Since the problem still seems to persist (including on current the Julia beta) I have opened an issue upstream. I guess since this is not a DocStringExtensions problem you can probably close this issue?

Thanks @lhupe.
