OK.
But don't go too far in writing actual code. I want to understand the use case at a high level (like how you started), then I can try to find how/if STON can do what you want. Right now, you are already too deep into a possible solution.
If I have to give a really simple use case.

Imagine an invoice.

The invoice has the name of the customer and the currency used as a class.

During the export of the invoice you do not want to export the currency
as a class but as a String.

So if I have an Invoice instance like this:

username: 'user'
currency: Currency[Euro]

I want to transform the currency to a string during the export. (and
keep the username as strings).

Result:

Invoice {
	#username : 'user',
	#currency : 'eur'
}

Instead of:

Invoice {
	#username : 'user',
	#currency : Currency {
				#unit: 'Euro'
			}
}

Then during the import I want to transform the currency into a class
again. (For example `Currency fromAbbreviation: stonInput`).
