Literals are never symbols. It is a special case for template 
alias parameter. But alias parameter itself it a symbol and thus 
can be used with normal alias. Variadic template argument list 
infers literal as a value, not as a template alias parameter. 
Values can't be used with normal aliases and thus it fails.
