Hello internals, After seeing some discussions about using enum values as keys, I thought of my own implementation of `nameof` (from C#) that is very hackish: https://github.com/withinboredom/nameof
I'd like to propose making it a real thing (with better behavior than my hack). An operator like this has a few niche uses, mostly for better error messages but also for making strings of things that you normally can't get the string value of. Here are some examples: nameof(func(...)) === 'func' nameof($party) === 'party' nameof($captain->planet) === 'planet' nameof(Class::Prop) === 'Prop' I first attempted this as an extension, but this belongs at the parsing/compiling level and not during runtime (this gets turned into a constant zval). I use my (very hacky) implementation to handle stringifying enums (mostly), as well as better, easier-to-refactor error messages: throw new InvalidArgumentException(nameof($var) . ' has an unexpected value'); Without it, the name of the variable can be missed in a refactor, making the error message useless or incorrect. The code to make this possible (without much error checking) is relatively simple: https://github.com/php/php-src/pull/11172 Robert Landers Software Engineer Utrecht NL -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: https://www.php.net/unsub.php
