> I've written a Ruby library that wraps the Avro Ruby library and provides a "registry" of schemas. The idea is to allow users to avoid repeating themselves by allowing inter-schema references using the type names. At runtime any missing type is resolved by loading the relevant schema from disk.
> This works great, but depends on parsing the error message from the Avro::SchemaParseError exception, extracting the name of the missing type. If there was a more specific subclass, e.g. Avro::MissingSchemaError, that provided an attribute with the name of the schema, my library would be a lot more robust. I'd rather not have everything break if you change the error message.
> I've added a PR here: https://github.com/apache/avro/pull/26
