Hi Doug,
Thanks for reading and for reply.

This is more like what I had in mind. Until I discussed this with another
Gora committer and saw the rest of your reply I was not sure if this should
be addressed on the Gora-side or if it is something we can work on for

This sounds sensible and much more in fit with what we are after. This was
more or less what we were trying to achieve by setting the default value to
null (within the compiler) on a field-by-field basis if no default value
was explicitly specified within the Avro schema. I think we'll progress on
this basis.

Thanks for the thoughts.
