I have to admit that I am now more confused than before. Is the lookup
problem in my OP a bug or not? And if not and the niebloids are there to
avoid clashes why don't they do their job in my case? The first example
in the cited answer is equivalent to 

find(begin(v), end(v), 47)

in my OP. This works with either "using" directive but not both which I
understand since the iterator variant of find is declared in both. But
with my original "find" there should be no clash since nothing in std::
matches.
