So how about the following suggestion:

- You write your -export declarations, properly, for soft.eng. purposes.
- For development & debuggning, put in a -compile(export_all) also!
- Let the compiler and/or otp *warn* if you're using something exported by an export_all
  but not a proper -export.

I imagine that to make a proper job of the last point, the compiler needs to put 
additional information in the beam file, namely mark the functions export_all:ed but not
exported.
