 Coq offers two mechanism that are suited to solve this task: typeclasses and canonical structures.
 Both can be instrumented in different ways to obtain a (more or less) convenient-to-use algebraic hierarchy.
 A common approach using typeclasses is the ["unbundled" approach by Bas Spitters and Eelis van der Weegen](https://arxiv.org/abs/1102.1323).
-However, as [has been observed before](https://pastel.archives-ouvertes.fr/pastel-00649586), and as learned the hard way in the Coq formalization of the [original Iris paper](http://iris-project.org/pdfs/2015-popl-iris1-final.pdf), this approach quickly leads to terms that seem to be exponential in size.
