5ad6d5cbc4 feat(kernel/converter): add eta-expansion to converter, this is important when terms contains metavariables 
For example, consider the unification constrains

    fun (x : A), f (?m x)  =?=  f

Eta-reduction is not applicable since (?m x) is not a variable.
However, if we eta-expand the left-hand-side, we get

   fun (x : A), f (?m x)  =?=  fun (x : A), f x

which is reduced to

      (?m x) =?= x

603dafbaf7 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.
