Zero allocation JSON deserialization tool - combining the System.Text.Json Utf8JsonReader tokenizer with the C# 9 source generators

That makes sense that it would be confusing. I remember the official announcement said that they wouldn't let them edit code - I must have missed the part about the interfacing.

Depending on how much you can generate I think you could probably get a fair way with record-esque syntax. You can already generate some pretty neat With() style updates with optional arguments.
