The Generator expression example for Icon can be simplified and does not require a co-expression.
<source lang=pascal>
local j
every j := (|seq(0) \ 20) ^2 do # Produced the first 20 squares
write(j)
</source>
If the idea is to demonstrate really what Icon can do in terms of using generators outside a loop construct, the following may be a better example
<source lang=pascal>
# find the first matching element
a := [1,2,3,4]
b := [5,6,2,7]
c := ( !a = !b ) | &null # assign first matching element, or set to &null
</source>
