Lean 4 fork for HoTT-compatible kernel extensions (Path types, transport, HITs). Maintained against upstream leanprover/lean4.

This PR fixes an issue where `x.f.g` wouldn't work but `(x.f).g` would when `x.f` is generalized field notation. The problem was that `x.f.g` would assume `x : T` should be the first explicit argument to `T.f`. Now it uses consistent argument insertion rules. Closes #6400. This also improves the algorithm for finding a relevant argument. Before it would try looking at the type and the whnf of the type, but now it iteratively unfolds types, checking each intermediate expansion. |
