I really like the split into two parts, to allow a direction word.

If you don't like the ::from, what about something like this?
    foo(convert(x).to<int>());
    optional<int> i = convert(x).to<int>(std::nothrow); // or maybe
.try_to<int>()

It's arguably the same as the .value() in Vladimir's lib, except that
by delaying providing the type, it makes sense that it's needed.

The scary implicit conversions might even make some sense when there's
no destination type:
    int i = convert(x);
