This was found in the gorilla-server generator, I don't know if this also happens for other server generators.

Generated code looks as follows:

// ------------- Optional query parameter "name" -------------
if paramValue := r.URL.Query().Get("name"); paramValue != "" {
    // this is empty
}

// BindQueryParameter

The if block has an empty body. I'm not sure if code is missing here, or if the whole if condition is superfluous.
