Lean 4 fork for HoTT-compatible kernel extensions (Path types, transport, HITs). Maintained against upstream leanprover/lean4.
Closures may capture huge objects that user may be unaware. For example, any closure created by the interpreter contains a reference to the `Environment`. @dselsam @kha I don't see many applications for maximizing sharing in values captured by closures. If we want this feature, we should at least wrap the `Environment` and `Decl` using external objects at `mk_stub_closure` at `ir_interpreter.cpp`. |
