- Explored whether or not it's possible to write recursive algorithms in

constant space using [[fs2]], and how it applies to [[sledge]].
|

- It was discussed in the Scala Discord whether or not there exists an

algorithm to generate moves for the Dragon Fractal in constant space. The
|

|
current theory is that there can't be an algorithm that uses less than

linear space.

- Completely disallows mutability in the source code to allow for better

optimizations, and to allow for returning variably-sized objects like

buffers or closures on the stack instead of the heap.
