Re: [RFC] Constant Scalar Expressions (with constants)

Hi Bob, thanks for your work, it’s awesome. One thing about constants: Take this example: const FOO = 2; class Klass { const FOO = 1; const BAR = FOO; } Here FOO is ambiguous, as it could resolve to 2 or to 1. If I understood it correctly, global constants are not yet implemented but I would suggest to always force prefixing the constant to get rid of the ambiguity and allow for future extension. const FOO = 2; class Klass { const FOO = 1; const BAR = self::FOO; } Does that make sense? cu, Lars On 07 Nov 2013, at 13:01, Bob Weinand <bobwei9@hotmail.com> wrote: > Hi! > > As you all know, Anthony Ferrara had withdrawn his RFC a few months ago, which was without > support for constants in these expressions: > > const foo = 10; > const bar = 10 * foo; > > The use of a constant in a declaration of a constant was not yet possible with his patch. > > That's what I changed. > > Enjoy reading the RFC at: > > https://wiki.php.net/rfc/const_scalar_exprs > > Bob Weinand > > Special thanks go to Dmitry who had helped me a lot with feedback and a deep review of the > patch. > -- > PHP Internals - PHP Runtime Development Mailing List > To unsubscribe, visit: http://www.php.net/unsub.php >
