#(1 3 4 5 7 -2) asVector
Meh.
Ugly.
{ 1. 3. 4. a. b } asVector
is the natural consequence.
v := (1,3,4,5,7,-2) asVector
keeps the parens. But why do I need to do that?
Autoformatting messing with my parentheses is just a mistake.
I put them in, leave them where they are, 'kay? I do not need an editor
that rewrites what I tell it. AST power or not.
And frankly, I like the "Feenk way of doing things" most of the time, so I
am willing to go that route.
