Maybe that "leak", namely observing whether a function is strict, is not something to care about. But here is what I think to be a possible way to remove it: Because `Function#arguments` and `Function#caller` do return `null` for sloppy functions in some circumstances (namely, when the function is not found in the call stack), let them always return `null` for non-sloppy functions. —Claude
