Hi Michael,
Good question!
{Point x:1 y:1. Point x:2 y:2.}
It’s not obvious! Notice the periods after the end of each element.
All the best,
Ron Teitelbaum

Subject: [Newbies] How does one create an array of points?
I've been trying to create an array of points (in Squeak 5) but am failing badly. See below: first part => what I get when I exec "print it" on the first part. Guidance please.
#(1 at 1 2 at 2) => #(1 #@ 1 2 #@ 2)
#((Point x: 1 y: 1) (Point x: 2 y: 2)) => #(#(#Point #x: 1 #y: 1) #(#Point #x: 2 #y: 2))
#(12 'b' $c) => #(12 'b' $c)
#(12 'b' $c 1 at 1) => #(12 'b' $c 1 #@ 1)
#(12 'b' $c (1 at 1)) => #(12 'b' $c #(1 #@ 1))
#(12 'b' $c (Point x: 1 y: 1)) => #(12 'b' $c #(#Point #x: 1 #y: 1))
Point x:1 y: 1 => 1 at 1
(Point x:1 y: 1) => 1 at 1
#((Point x: 1 y: 1)) => #(#(#Point #x: 1 #y: 1))
#(1 at 1) => #(1 #@ 1)
