A couple of notes:

The use of a variadic template parameter instead of an alias 
parameter is misleading because the template does not need to 
support types in the first place (and the proposed implementation 
would fail when given a type).

The name used on dlang.org is correctly using a lowercase `e`, 
according to the naming convention for templates that always 
evaluate to values/variables as opposed to types.
