Does it? AliasSeq's template parameter (singular) is named TList, not a, 
b, or c.

So I would expect this to fail to compile.

This does bring up a valid point though. The DIP talks about variadic 
parameters, but template variadic parameters actually have a name.

So what does this mean? Is it valid?

AliasSeq!(TList: 1, 2, 3)
