Currently, it is very hard to write tests for core. There are two main reasons for this: 1. The core parser is currently very rudimentary and it is not easy to write core programs. This would be addressed by a new core frontend (#1152). 2. The core pretty-printer is currently unable to produce code that can be re-parsed with the core parser. I would like to address this with this PR. While a new core frontend would subsume both of these problems, it is a lot more effort than adding a re-parsable mode to the current core pretty-printer. This would allow us to compile source programs to core and pretty-print them to use them as golden output in core tests. In particular, when developing the new normalizer (#1127), I would like to track its behavior in unit tests, but they are currently very time-consuming to write due to the fact I cannot just use pretty-printed core for comparison.
