    Completer which can be used for autocompletion according to variables in
    the grammar. Each variable can have a different autocompleter.

    :param compiled_grammar: `GrammarCompleter` instance.
    :param completers: `dict` mapping variable names of the grammar to the
                       `Completer` instances to be used for each variable.
