commit 6193f6d07f380436048928182ef511f167909a53
Author: Ben Gamari <ben at smart-cactus.org>
Date:   Sun May 22 12:42:23 2016 +0200

    Don't consider default class ops when looking for decls
    
    When we are looking for an operation within a class we don't care about
    `default`-type declarations. This was the cause of #505.
