Suppose I'm writing a function taking in an iterable, and my function wants to be agnostic as to whether that iterable is actually an iterator yet or ...

To phrase the question differently: if we were to remove termination-checking and the guardedness condition on uses of inductive and coinductive data ...
This is a corecursive algorithm, because with each iteration it calls itself on data that is greater then what it had before: It is similar to tail ...
Corecursion means calling oneself on data at each iteration that is greater than or equal to what one had before. Corecursion works on codata, which a ...
I am experimenting with the definition of CoNat taken from this paper by Jesper Cockx and Andreas Abel: I define zero and plus: And I define bis ...
I'm trying to implement a type that represents a (possibly) infinite path on an infinite binary tree. The definition currently resembles that of Conat ...
There is filter : (a -> Bool) -> List a -> List a for List, but there is no filter : (a -> Bool) -> Stream a -> Stream a for Stream, ...
We can not store a decimal in infinite precision, but there may be some way to represent them just like we represent infinite lists in haskell. The f ...
There is some explanation here. Intuitively I understand how finite data structures differ from infinite data structures like streams. Nevertheless, i ...
Imagine the following function to give an infinite lazy sequence of fibonacci in Clojure: Assuming We take the pithy definition of codata as b ...
In terms of pithy summaries - this description of Comonads seems to win - describing them as a 'type for input impurity'. What is an equivalent pithy ...
