> I meant that it would have to decode the entire EDN string literal containing the base64 data before decoding the base64

yes, any edn reader implementation will read the complete base64 string from the example before giving this string to a custom reader. I understand now what you explain. However, I don't know what I can do about it. I use edn daily, it works great to me, and I have no immediate plans to replace it with something else.

Anyway, the example you shared looks interesting, I'll definitely read more about it. Thank you.
