in Delphi 10.2.1, there is new support for debug visualizers for generics... https://community.embarcadero.com/blogs/entry/new-in-10-2-1-debug-visualisers-for-delphi-generics
When debugging, it would also be interesting to see,
- which types are registered in the container
- which instances are actually living inside the container
As this would be very nice for debugging Spring4D, could you implement this?
