About `auto-expansion` problem: please add documentation that

don't
know any difference, probably because I didn't write too
complicated meta code.
Added, does this help:
http://wiki.dlang.org/DIP54#Auto-expansion_explained ?
Oh, I see. Thank you for the example. It really looks like
`TemplateArgumentList without auto-expansion` is more generic
solution.
Please, add similar example to the Phobos documentation (for
example, to the `http://dlang.org/tuple`) when you will implement
this DIP.
Also, can we keep bouth `auto-expansion TypeTuple` and
`TemplateArgumentList whitout auto-expansion` (maybe, in a
different module)?
Technically - yes. But I think it will cause more damage that
help.
Or, maybe, can we add documentation how to
convert any `auto-expansion TypeTuple` to the
`TemplateArgumentList without auto-expansion`.
Like this?
alias Packed = TemplateArgumentList!(T); // assuming T is
variadic template argument list, T...
alias Expanded = Packed.expand;
Yes, exactly.
Can we add alias for `auto-expansion TypeTuple` and add link to
the previous documentation like this:
alias ExpandedTemplateArgumentList(T) =
TemplateArgumentList!(T).expand;
It looks like it can fix all objections here.
