Comment (by goatbar):

 And there are some easy to find instances of the same thing:

 {{{
 find . -name \*.cpp | xargs egrep '[.]size()' | egrep '== *0|0 *=='
 ./geomgraph/EdgeEndStar.cpp:    if (edgeMap.size()==0) return nullCoord;
 ./geomgraph/EdgeEndStar.cpp:    if (edgeMap.size()==0) return true;
 ./operation/buffer/SubgraphDepthLocater.cpp:    if
 (stabbedSegments.size()==0) return 0;
 ./operation/overlay/LineBuilder.cpp:    if ( v3d.size() == 0 )
 ./linearref/ExtractLineByLocation.cpp:  if (newCoordinateArray.size() ==
 0)
 }}}
