Frankly, I see nothing wrong with the idea. Its really the same as "0 !=
c.size()" or " ! c.empty()".
With, as Arthur pointed out, the benefit of being able to instantiate
something like a range in a conditional, just extended to containers:

Ex:

dlg.clearList();
if( auto resVec = dbc.submit( query ) )
{
  dlg.populateList( resVec );
}
