    SignatureArray *arr = rdx_method_alias_definition_signatures(graph, data->id);
    return rdxi_signatures_to_ruby(arr);
}

#target ⇒ Rubydex::Method?

Returns the resolved target method declaration by following the alias chain, or nil if the chain could not be resolved. Raises Rubydex::AliasCycleError when the alias chain forms a cycle.
