list

Returns f applied to the contents of as if non-empty, otherwise, the zero element of the Monoid for the type B.

[(as(0), as(1)), (as(1), as(2)), ... (as(size-2), as(size-1))]

Combinations of as and as, excluding same-element pairs.

spanM with p's complement.

Run p(a)s left-to-right until it yields a true value, answering Maybe.Just(that), or Maybe.empty if nothing matched p.

As with the standard library groupBy but preserving the fact that the values in the Map must be non-empty

groupWhenM specialized to scalaz.Id.Id.

Split at each point where p(as(n), as(n+1)) yields false.

[Nil, as take 1, as take 2, ..., as]

Intersperse the element a between each adjacent pair of elements in as

All of the Bs, in order, and the final C acquired by a stateful left fold over as.

All of the Bs, in order as-wise, and the final C acquired by a stateful right fold over as.

scala.Nil with a sometimes more convenient type

A pair of passing and failing values of as against p.

A pair of the longest prefix of passing as against p, and the remainder.

[as, as.tail, as.tail.tail, ..., Nil]

Run p(a)s and collect as while p yields false. Don't run any ps after the first true.

Run p(a)s and collect as while p yields true. Don't run any ps after the first false.
