// Thoughts on Universal Data language / description
// See: https://martin.kleppmann.com/2012/12/05/schema-evolution-in-avro-protocol-buffers-thrift.html#comment-2534873305
/* Preface:
Why do Thrift, Protobuf, and Avro each define their own IDL?
I would think that there could be an implementation-independent "master" IDL
to standardize the syntax (the semantics depends on the feature set of the implementation).
It makes it hard to try out these different libraries when they require rewriting
the message schema each time.

Mocha users need to watch out for this surprising behavior
View README.md

Mocha does not reload modules when running multiple tests. This can lead to some curious errors that are difficult to understand at first, but have to do with modules that have an internal state of their own. If you have a folder with two files, test1.js and test2.js (shown in gist below), you will find you get different test results even though they are identical except in name. The first one fails, but the second succeeds.

So some state from previous tests can "pollute" later tests. This makes it difficult to write unit tests in isolation with Mocha, because suddenly when you put both tests together in the same directoy, mocha's behavior can break the tests.
