I'm curious how field registry can be a compile-time definition, if it depends on a part-vector which would have run-time contents.

I was thinking the type look up could be moved to compile time so that when fields are accessed we wouldn't have to include the type. Registry would still have to be runtime. However, looking at the dependencies I'm not sure I want to do that anymore. We'd have to expose more of the field information across the code base instead of isolating it to a single *.C file. This could wreak havoc on the compile times. After we convert to the simple fields the type information becomes way less cumbersome for accessing fields. So I think we should keep it as is.

It's nice to be able to remove these modify and sync calls.
