I've written a variadic template that accepts a variable number of char parameters, i.e.

template <char... Chars>
struct Foo;

I was just wondering if there were any macro tricks that would allow me to instantiate this with syntax similar to the following:

Foo<"abc">

or

Foo<SOME_MACRO("abc")>

or

Foo<SOME_MACRO(abc)>

etc.

Basically, anything that stops you from having to write the characters individually, like so

Foo<'a', 'b', 'c'>

This isn't a big issue for me as it's just for a toy program, but I thought I'd ask anyway.
