Weird, but what do I know.

 

I see that this (a period separating each from the next) also works:

 

{1 at 1. 2 at 2. 3 at 3} => {1 at 1 . 2 at 2 . 3 at 3}

 

[Ron Teitelbaum] Ahh Yes.  Even better.

 

Thanks, all.

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,

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)
