I'm not too worried about having to import. It's more of the fact 
that these are going to be mangled with the package/module name 
(though the mangling backreference system will limit this a bit).

I should probably actually test and see what it looks like.

I thought of `IHeader` but that looks like an interface...

I also thought of `IESHeader` but this is less obvious to someone 
who sees it.

InterpHeader is still long, but a bit better. Any reduction is 
better than no reduction?
