@targos I'm getting a runtime error with this. Am I missing something?

NOTE: The test started as a child_process using these flags: [ '--expose-internals', '--no-warnings', '--allow-natives-syntax' ] Use NODE_SKIP_FLAG_CHECK to run the test with the original flags.

I'm getting a runtime error with this. Am I missing something?

I think it's because you can't directly optimize a native function. You need to wrap it in a JS function and optimize that.
