fix(frontends/lean/inductive_cmd): inductive datatype elaborator was 'fixing' parameter mismatches.
...
Given a datatype C with parameters As, if the declaration contained
(C Bs), the elaborator would silently replace it with (C As).
This bug would confuse users and make them believe they define something
different.

fix(frontends/lean/calc_proof_elaborator): bug when inserting symmetry proofs for heq, fixes #286
...
The problem was that heq type is
Pi {A : Type} (a : A) {B : Type} (b : B), Prop
The calc_proof_elaborator was assuming that (a : A) (b : B) were the
last two arguments in any relation supported by calc.
The fix is to remove this assumption.

- `by tactic`

- `{ expr }`
