Currently there's no way to remember something between executions of your brush. There should be a function that can initialize, store, and modify state. Something like

withState
  init : \() -> T
  draw : \T -> [scribble, T]

init gets called to initialize a state value T, which is remembered across invocations
draw returns a list with a scribble to be drawn, along with an updated T

Unsolved problems:

We don't have a GC. We're probably gonna need some way of snapshotting values and then restoring them in a VM execution later on, after ref slots and memory usage has been cleared.

Currently there's no way to remember something between executions of your brush. There should be a function that can initialize, store, and modify state. Something like ``` withState init : \() -> T draw : \T -> [scribble, T] ``` - `init` gets called to initialize a state value `T`, which is remembered across invocations - `draw` returns a list with a scribble to be drawn, along with an updated `T` Unsolved problems: - We don't have a GC. We're probably gonna need some way of snapshotting values and then restoring them in a VM execution later on, after ref slots and memory usage has been cleared.
