yes, i just saw this in one of the two videos on kickstarter.
it lets you manually filter the output of ls for example.

greetings, eMBee.

pike can do something like that:

Pike v7.6 release 7 running Hilfe v3.5 (Incremental Pike Frontend)
> array a=({ 1, 2, 3 });
> array b=({ 4, 5, 6 });
> array c;
> c=a[*]+(2*b[*])[*];
(1) Result: ({ /* 3 elements */
9,
12,
15
})

the automap operator [*] maps each element of the vector into the equation one by one. i have seen one other language that has such a feature, but i don't remember what it was.

greetings, eMBee.
