Proof using: let-in policy, optional auto-clear, forward closure*
- "Proof using p*" means: use p and any section var about p.
- Simplify the grammar/parser for proof using <expression>.
- Section variables with a body (let-in) are pulled in automatically
since they are safe to be used (add no extra quantification)
- automatic clear of "unused" section variables made optional:
Set Proof Using Clear Unused.
since clearing section hypotheses does not "always work" (e.g. hint
databases are not really cleaned)
- term_typing: trigger a "suggest proof using" message also for Let
theorems.
