Hi everyone,

for today a very simple question: why does Cthulhu seemingly shows

this question is so basic that I feel like I must be missing something.

```
julia> function overwrite!(arr)
arr[1] = zero(eltype(arr))
return arr
end
overwrite! (generic function with 1 method)
```

This function is obviously not type unstable, but Cthulhu reports that `setindex!`

returns `Any`

.

```
julia> @descend overwrite!(zeros(3))
overwrite!(arr) @ Main REPL[3]:1
1 function overwrite!(arr::Vector{Float64})::Vector{Float64}
2 arr::Vector{Float64}[1] = zero(eltype(arr::Vector{Float64})::Type{Float64})::Float64
3 return arr::Vector{Float64}
4 end

```

`@code_warntype`

doesnt show anything (as expected)

Is this expected, or a bug?
