この例は３つの配列の演算子を実演します。
{{{
def endangered = ['Caribou', 'Ocelot', 'Puma', 'Sei'];
println( endangered );
def flipped = reverse endangered;
println( flipped );
println( sizeof endangered );
for (mammal in endangered) {
   println( 'Mammal #{ indexof mammal } is { mammal }' );
}
}}}

コンソールは次のようになります。
{{{
[ Caribou, Ocelot, Puma, Sei ]
[ Sei, Puma, Ocelot, Caribou ]
4 
Mammal #0 is Caribou 
Mammal #1 is Ocelot 
Mammal #2 is Puma 
Mammal #3 is Sei
}}}
