I think we should use this chance to rectify the capitalization 
of the name. As the result is not exclusively a list of types, 
current conventions state that the name should be lowerCamelCase.

I also think it should be shorter, because a) it's a fundamental, 
and thus very commonly used template, and b) code that 
manipulates lists are functional in nature which results in long 
lines that are also hard to split up because sometimes they are 
in template constraints or function template parameter lists etc.

I like the name `list`.
