Hi,  
I’m in the process of writing a package for scraping a particular API ([see here](https://github.com/danielw2904/ChartmetricScraper.jl)) and I am getting “Possible method call error” for two types of calls.

The first is when calling `parse` from the `JSON` package (the API response is always a JSON object). Possibly related: If I hover the mouse over `parse` I get the help for the `Base.parse` function.

```julia
function parseresponse(response::HTTP.Messages.Response)
    bod = response.body
    ret_dict = JSON.parse(String(bod)) # <- Possible method call error
    return ret_dict
end

```

The second type is when I quote a request and then try to `eval` it. I do this because I want to run the request, get the response and then based on the response code do something (i.e. wait until the next minute if the rate limit is hit) and then retry the same request:

```julia
function eval_example(url, header)
    req = :(HTTP.request("GET",
                $url, $header, status_exception = false))
    resp = eval(req) # <- Possible method call error
    return resp
end

```

Any ideas how I could resolve those?

Thanks!

Confirmed (latest VSCode 1.47.2 and Julia extension 0.17.6, Julia 1.4.2). Could be a bug/missing feature in [Language Server](https://github.com/julia-vscode/LanguageServer.jl) @davidanthoff ?
