The new `partial def`s allow us to define `fix` in Lean, but the Lean implementation is not as efficient as the native one. The native one in C++ use weak pointers to prevent a closure allocation at every recursive invocation. This commit also fixes the `fixCore` helper functions that were broken after we switched to camelCase. We have updated the test `fix1.lean` to demonstrate the native implementation is faster. Here are the numbers on my desktop. ``` ./run.sh fix1.lean 24 721420279 Time for 'native fix': 816ms 721420279 Time for 'fix in lean': 1.34s ``` |
