From our benchmarks we can see that we are consistently slower than everyone else when serializing/deserializing boolean values. We should fix that.

orjson is using an unsafe block to create a reference to a boolean:

This avoids additional allocations.
For comparison, this is our code at the

We get the return annotation for free, so we should allow users to do something with it.

We use example files inside the generated module, and also outside of that module. It might make sense to move the fixtures directory outside the generated module.
