If it is you judgement, let it be so. I prefer to start working on
implementation whatever it is as opposed to endless discussion. What is
your opinion about defining general guideline to use packs over nested
templates for multi-list algorithms (another disagreement between me and
Jakob)?
I think an argument advocating a bunch of changes that add chaff to
code that works very well would have a hard time geting off the
ground. Use the right tool for the job - that's why we're providing
two of them.
It is not related to any existing code as there are no multi-list
templates in std.typetuple right now. What I am speaking about is
defining new ones in two possible ways:
template Equals(T1...)
{
template To(T2...)
{ ... }
}
vs
template Equals(alias T1, alias T2)
if (isTemplateArgumentPack!T1 && isTemplateArgumentPack!T2)
{
}
I think default Phobos style should be the latter while Jakob seems to
favor the former. Judgement of uninterested party is welcome.
I think the latter style is more natural.
