- Bugs are easier to trace down to one stage.
|

- Stages are also replacable, pluggable and usable somewhere else.
|

- For example,
|

one could write a Just-In-Time compiler as a new executor to replace the runtime stage,
|

one could write a Just-In-Time compiler as a new evaluator to replace the runtime stage,

while preserving the source #arrow() graph IR step.
|

However, this also makes the architecture somewhat more complicated. So here we try our best to describe how each stage looks like. If you have any feedback, feel free to drop it on #link("https://forge.katzen.cafe/katzen-cafe/iowo/issues")[the issues in the repository]!
