Use template classe for extraction of values ?

[Luthaf]

The interface would be nicer if we could do

auto out = args["--output"].as<std::string>();
auto num = args["--num"].as<size_t>();

instead of

auto out = args["--output"].asString();
auto num = args["--num"].asLong();

I do not know if this is possible of not.

It would be possible. However given that there are only 4 options, I'm not sure there would be a strong benefit to it.

Mainly to silent compiler warning while doing

int num = args["--num"].asLong();

But I do agree this is not a big feature.
