Chai-like expressive language & readable style

[PaulRBerg]

From chaijs.com:

foo.should.be.a('string');
foo.should.equal('bar');
foo.should.have.lengthOf(3);
tea.should.have.property('flavors')
  .with.lengthOf(3);

It should be possible to do this in Solidity v0.8 with user-defined value types. Looks like OlympusDAO has implemented something like this in their test-utils repository.
