Lean 4 fork for HoTT-compatible kernel extensions (Path types, transport, HITs). Maintained against upstream leanprover/lean4.
This PR generalizes the `while` syntax in `do` blocks so that the condition can be any `doIfCond`, the same condition form already accepted by `if`. As a result, `while let pat := e do …` and `while let pat ← e do …` are now supported in addition to `while cond do …` and `while h : cond do …`. The previously separate `doWhile` and `doWhileH` parsers and their accompanying macros are unified into a single `doWhile` parser whose macro delegates to the existing `doIf` desugaring. |
