Subject: More explicit attribute deletion/detection - a lof of this is probably redundant... 
X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?a=commitdiff_plain;h=86cc339a6d3fd0dfd144f511c893affa897c19a2;p=dbsrgits%2FDBIx-Class-Historic.git

More explicit attribute deletion/detection - a lof of this is probably redundant, as _resoved_attrs() should flatten them away (i.e. prefetch to collapse and distinct to group_by). Nevertheless keep them there for explcetness ( delete() is cheap )
