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.
