Impressive. But having to return [[x, y, z]] instead of [x, y,z] is a
compromise.
I was trying to translate Python list-comprehensions into Javascript
and here is what I've come up with.
$pyjs.listcomp(
function(x, y, z) { return [x, y, z]},
[
range(1, 100),
function(x) { return range(x, 100)},
function(x, y) { return range(y, 100)},
],
function(x, y, z) { return x*x + y*y == z*z;}
)
I haven't worked out the $pyjs.listcomp function implementation yet.
