This module provides an Interpret
able data type of "linked list of
tensor applications".
The type
, for any Chain
t
, is meant to be the same as
Tensor
t
(the monoidal functor combinator for ListBy
tt
), and represents
"zero or more" applications of f
to t
.
The type
, for any Chain1
t
, is meant to be the
same as Associative
t
(the semigroupoidal functor combinator for NonEmptyBy
tt
) and
represents "one or more" applications of f
to t
.
The advantage of using Chain
and Chain1
over ListBy
or NonEmptyBy
is that
they provide a universal interface for pattern matching and constructing
such values, which may simplify working with new such functor
combinators you might encounter.

Chain
A useful construction that works like a "linked list" of t f
applied
to itself multiple times. That is, it contains t f f
, t f (t f f)
,
t f (t f (t f f))
, etc, with f
occuring zero or more times. It is
meant to be the same as
.ListBy
t
If t
is Tensor
, then it means we can "collapse" this linked list
into some final type
(ListBy
treroll
), and also extract it back
into a linked list (unroll
).
So, a value of type
is one of either:Chain
t i f a
i a
f a
t f f a
t f (t f f) a
t f (t f (t f f)) a
 .. etc.
Note that this is exactly what an
is supposed to be. Using
ListBy
tChain
allows us to work with all
s in a uniform way, with
normal pattern matching and normal constructors.ListBy
t
You can fully "collapse" a
into an Chain
t i ff
with
retract
, if you have
; this could be considered
a fundamental property of monoidness.MonoidIn
t i f
Another way of thinking of this is that
is the "free
Chain
t i
". Given any functor MonoidIn
t if
,
is a monoid
in the monoidal category of endofunctors enriched by Chain
t i ft
. So,
is
the "free Chain
Comp
Identity
Monad
",
is the "free Chain
Day
Identity
Applicative
", etc. You
"lift" from f a
to
using Chain
t i f ainject
.
Note: this instance doesn't exist directly because of restrictions in typeclasses, but is implemented as
Tensor
t i =>MonoidIn
(WrapHBF
t) (WrapF
i) (Chain
t i f)
where pureT
is Done
and biretract
is appendChain
.
This construction is inspired by http://oleg.fi/gists/posts/20180221singlefree.html

Chain1
A useful construction that works like a "nonempty linked list" of t
f
applied to itself multiple times. That is, it contains t f f
, t
f (t f f)
, t f (t f (t f f))
, etc, with f
occuring one or more
times. It is meant to be the same as
.NonEmptyBy
t
A
is explicitly one of:Chain1
t f a
f a
t f f a
t f (t f f) a
t f (t f (t f f)) a
 .. etc
Note that this is exactly the description of
. And that's "the
point": for all instances of NonEmptyBy
tAssociative
,
is
isomorphic to Chain1
t
(witnessed by NonEmptyBy
tunrollingNE
). That's big picture
of NonEmptyBy
: it's supposed to be a type that consists of all possible
selfapplications of f
to t
.
Chain1
gives you a way to work with all
in a uniform way.
Unlike for NonEmptyBy
t
in general, you can always explicitly /pattern
match/ on a NonEmptyBy
t fChain1
(with its two constructors) and do what you please
with it. You can also construct Chain1
using normal constructors
and functions.
You can convert in between
and NonEmptyBy
t f
with Chain1
t funrollNE
and rerollNE
. You can fully "collapse" a
into an Chain1
t ff
with retract
, if you have
; this could be considered
a fundamental property of semigroupness.SemigroupIn
t f
See Chain
for a version that has an "empty" value.
Another way of thinking of this is that
is the "free
Chain1
t
". Given any functor SemigroupIn
tf
,
is
a semigroup in the semigroupoidal category of endofunctors enriched by
Chain1
t ft

is the "free

Bind
",
is the "free
