To provide interactive experience, Leporello.js traces calls to IO functions
made by your app and can later replay them from trace, allowing to program by
making small iterations on your code and instantly getting feedback.

compare arguments for equality, Leporello.js uses deep equality comparison with
`JSON.stringify`. Otherwise, the cache gets discarded, and Leporello.js

If you want to bust cache manually, there is a button and a hotkey for this.
