Is this the first call to register something that we have in the serialization
system? It would be nice to keep it that way. I'm ok submitting this as is, but
maybe it is worth investigating the alternatives at this time.

I'll look into it now (I have a solution in mind).

+          // instead.
+          _compiler.backend.constants.registerLazyStatic(element);
