Propose dropping ‘using namespace std‘

[goatbar]

Pulling in whole namespaces is now generally considered bad form. It pollutes the compilation unit and it is hard for the reader to know what to expect.

Are folks okay if I work through removing them?

I agree in what your mentioning, In fact, in the files I am working on, I am changing the:

using namespace a::b::c;

to the set of classes used on the namespace

using a::b::c::Class1;

In d271aaa/git:

Remove use of 'using namespace std'. References #915
