905209df1c fix(frontends/lean/elaborator): to cache values, we must push/pop whenever we update the m_ctx 
Thus, we are disabling the cache for now.

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.
