<p class="MsoNormal">I am designing a behaviour that extends gen_server and thus I want all of gen_server’s callback specification in addition to some additional ones on top as part of the extension. In the past I have favored using the `-callback` attribute
as recommended in the documentation but then I saw someone recommend the following when extending gen_server<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">> behaviour_info(Type) -> gen_server:behaviour_info(Type).<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I tried combining the two approaches but such is not allowed (which makes sense). I believe my options are to append my callbacks to gen_server’s list using `behaviour_info` or to copy gen_server’s callback specifications from the OTP
source. Copy-pasting code just feels wrong... how bad is it to use `behaviour_info` over `-callback`? And am I taking the right approach?<o:p></o:p></p>
