In the meanwhile there may be a chance for a general solution [in sight](https://discourse.julialang.org/t/this-month-in-julia-world-2024-05/115278/1)

> This might be changing soon (enabling Revise to redefine structs). See this [old proposal](https://github.com/JuliaLang/julia/issues/40399) and [recent (well documented) work on implementation](https://github.com/JuliaLang/julia/pull/54654).

and most probably the problem is above my competence anyway. Still, the following idea, rather vague one:

```julia
module Module_Foo
    struct Foo
        x::Int
    end
end
Foo = Module_Foo.Foo

# now we want to re-define Foo
fm = methodswith(Foo)

sources = [m.source_ref for m in fm] # pseudocode

# delete "old" methods
for m in fm
    Base.delete_method(m)
end

# re-define Foo
module Module_Foo
    struct Foo
        x::Int
        y::Int
    end
end
Foo = Module_Foo.Foo 

for s in sources
    recompile(s) # pseudocode
end

```

in separate place:

```julia
foo(a::Foo) = a.x

```

Any idea what to put on the place of the pseudocode?
