In both cases, identifiers are visible at global scope, thus, they have just
exactly the same probability of clashing with other names at compile time.

Do you mean that the extern '_1' may clash at link time? Well, that's
true... though very unlikely, IMHO.
If possible clashes are at stake, they can go in ::boost, or have other
names as has been suggested.

Another alternative which I also suggested is to get rid a the 'variable'
and use an inline function: _1()
