View on Github →fix a typo in Topology.Homotopy.Basic (#2921)
The prop' field used continuous_to_fun instead of continuous_toFun. Lean 4 silently introduced an implicit argument continuous_to_fun, so one had to specify it in the .prop theorem below.
Also golf a proof using new Lean 4 rfl for structures.
