You can generate reflection data at compile-time to use at
runtime.

For an example, you can take a look at
https://shardsoft.com/stash/projects/SHARD/repos/shardtools/browse/source/ShardTools/Reflection.d
(docs: https://shardsoft.com/docs/ShardTools/Reflection.html). I
wouldn't use the file/repo directly, but feel free to take
anything you find useful from it.
