Underscore cleanup happening in early return

[Victorious3]

The function in question in server.pr:

def go_to_definition(id: int, params: DefinitionParams) {
    let path = uri_to_path(params.textDocument.uri)
    let module = toolchain::find_module_by_path(path)
    if not module { send_reply(id, null); return }	
    let node = find_node_at(module, params.position)
    if not node { send_reply(id, null); return } // <- Cleanup of the underscore happens here
    
    var sloc: parser::SourceLoc
    
    let name, _ = find_member(node) // <- Underscore should come in here
    ...
}

Clearly this is some bug with a variable being used before its defined.
