Hello, internals! What do you think about creating shorthand `number` for `int|float`?

nothing because: a) float accepts int anyways b) overloading the engine for each and every nuance is not helpful c) union types are clear and readable

...and introducing 'number' would also be a huge BC break (even in our codebase there's a class named 'Number'). Best regards, Benas On Sun, Nov 8, 2020, 7:26 PM Reindl Harald (privat) <harry@rhsoft.net> wrote:

If at all, it should be called `numeric`, because that is a reserved word as of PHP 7.0.0: <https://www.php.net/manual/en/reserved.other-reserved-words.php>.

ACK. See <http://svn.php.net/viewvc?view=revision&revision=351123>.

Others have pointed at a few reasons why not, but I'd like to add that if we allow type aliasing, then projects can choose to define this or not. I'd rather see the power (and tradeoffs) placed in the hands of script developers. -Sara

Agree with what has been said. We probably should leave this "alias" discussion to a near future where people would be able to create their own types like so: ```php type Number = Foo|Bar; ``` - Nuno On Mon, 9 Nov 2020 at 16:25, Sara Golemon <pollita@php.net> wrote:
