Why are the variadics written in lower case?
Per the style guide,
=====
Eponymous Templates
Templates which have the same name as a symbol within that
template (and instantiations of that template are therefore
replaced with that symbol) should be capitalized in the same way
that that inner symbol would be capitalized if it weren't in a
template - e.g. types should be PascalCased and values should be
camelCased.
=====
So, whether an eponymous template is camelCased or PascalCased
depends entirely on what its result is. It's quite possible that
there are older symbols in Phobos that don't follow those
guidelines, but most do. However, there are some where it's not
clear which it should be.
e.g. std.meta.Filter is a funny one, because it works with any
symbol - be it a type or a value - so it could have gone either
way, but it was probably targeted primarily at types, so it ended
up with its name being PascalCased.
But in general, an eponymous template which results in a type is
supposed to be PascalCased, whereas the others are supposed to be
camelCased.
Really, pretty much anything that isn't a type is camelCased,
whereas types are PascalCased. It's just that there a few cases
that are inherently ambiguous, and there may be some older
symbols in Phobos which don't properly follow the current style
guide.
