It’s here now: https://thomasperi.github.io/clumpyjs/nesting
To nest loops, just put a chain or a loop in the statements block of another loop. They can be nested indefinitely.
var i, j;
clumpy.
for_loop(
function () { i = 0; },
function () { return i < 100000; },
function () { i++; },
function () {
clumpy.
for_loop(
function () { j = 0; },
function () { return j < 5; },
function () { j++; },
function () {
// statements
}
).
once(function () {
// statements
});
}
);
