Hi, `stats()` and friends invoked with empty string or null as argument, return `false` (indicating failure), but do not emit the Warning that is expected on failure. See: https://3v4l.org/jXC2N <https://3v4l.org/jXC2N>
That discrepancy between the two ways of indicating failure is problematic. Indeed, whenever I use one of those functions without prefixing it by @, I expect that it will either return a value of expected type (`array` in case of `stats()`), or run the panic procedure of my error handler. I propose to ensure that those functions always emit a Warning in each and every situation they return false/null (provided, of course, that those functions are not supposed to return `false/null` in absence of failure, and that their purpose is not to check failure condition as in `file_exists()`). —Claude
