Could we add unit tests for this change?

[AlexRMU]

I see that more tests need to be added for getAll and getAllAndOverride, as well as more type checks for all.
It is better for the members to do this or create a separate issue.

Hi, this won't involve any breaking change ?

[AlexRMU]

For those who used a decorator with transformation, the return type was unknown, and now it will become TTransformed.
Nothing will change for the others.
