It is not clear whether this is a good idea or not. In some cases, it seems to do more harm than good.

refactor(kernel): remove 'let'-expressions
...
We simulate it in the following way:
1- An opaque 'let'-expressions (let x : t := v in b) is encoded as
((fun (x : t), b) v)
We also use a macro (let-macro) to mark this pattern.
Thus, the pretty-printer knows how to display it correctly.
2- Transparent 'let'-expressions are eagerly expanded by the parser.
