would this work?

auto x = Set!(int);

it's not quite as clean but...


If you don't like that 

you could try having set used as above take 2 things plus a tuple, then have 
a version of the template that takes one type and has function that take 
one or zero arguments

Set!(T) set(T, U, V...)(T e1, U e2, V elements) {...}

template set(T)
{
Set!(T) set(T e1) {...}
Set!(T) set() {...}
}

again, not as clean but, it could work.

I haven't tried this so it may not work.
