Lean 4 fork for HoTT-compatible kernel extensions (Path types, transport, HITs). Maintained against upstream leanprover/lean4.
This PR moves the new compiler's noncomputable check into toMono, matching the recent change in the old compiler. This is mildly more complicated because we can't throw an error at the mere use of a constant, we need to check for a later relevant use. This is still a bit more conservative than it could theoretically be around join points and local functions, but it's hard to imagine that mattering in practice (and we can easily enable it if it does). |
