Yes, yes, yes, 20 times yes. There are some quirks with what can 
be aliased depending on how the alias is declared, this needs to 
be unified.

The thing we are naming here is some collection of aliases. 
Talking to everybody, the 2 names that came up frequently for 
this collection are List and Sequence. I personally don't mind, 
but Walter had strong views against List, so I went for Sequence.

Now we should decide for a term for this entity we have in D that 
is kind of tuple but auto unpack. This construct does not exists 
in other languages, so, as explained by Jonathan, no existing 
name will fit 100% . I'd say we pick some name that evoke an 
ordered collection and that which is not already used for some 
existing construct in D (which rules out array for instance) or 
have a well defined meaning (like tuple).

Sequence fit the bill. I don't mind using another name that fit 
the bill as well. Nobody came up with that name yet.
