I personally don't consider it a problem, and I think it would be a
bad idea to marry the namespace management to the implict naming
scheme of the record-defining form. There are many open questions and
potential problems associated with it. (What if any of the names
exported implicitly wasn't defined implicitly? ...)
All the reasons I've given for avoiding implicit naming in the first
place apply here in even more relevant form. When I can't even grep
the module definitions for exported names, I'm (personally) in serious
On the practical side:
- More often than not I *don't* want to export all the names defined
by a record-definition form.
- In the ten years I've lived with listing all the exported names
explicitly (after having named them explicitly), I've never felt
this to be a problem---it also never came in as a reported problem
from the Scheme 48 users, and we've sure seen many record
definitions with many fields as well as bindings for Xlib.
