qsort@r$[] [H@T] = [@T.keep{?<H}^r H @T.skip{?<H}^r]

qsort /function name
@r$ /recursive alias r ?
[] /empty list?
[H@T] /list arg H first list element // T last list element?

=

[@T.keep{?<H}^r H @T.skip{?<H}^r]

== [qsort{@T.keep{?<H}} H qsort{@T.skip{?<H}}] ?

~== list(quicksort(list < H ), H, quicksort(list > H))
