Thanks.
What about construction and assignment from a static array of
`Pair`'s? Wouldn't that be easier on the compiler?

The first function will be used. Shouldn't the template argument (T :

There is also template constraints which may be useful:

OK, so I have a situation where I'm foreaching over a compile-time list

Inside that loop, I'm using a switch on the input, and inside the

I you refer to it wouldn't be using templates, then yes, I guess
so.

With the `-verrors=1` flag. You can specify exactly how many
errors the compiler should emit before halting the compilation.
Specify `0` for unlimited.
