Re: [PHP-DEV] Re: [Zend Engine 2] Re: [PHP-DEV] namespaces ambiguity
why not = then. imo the parser will easily distinguish array definition from an expression b. - Original Message - From: Andi Gutmans [EMAIL PROTECTED] To: Zeev Suraski [EMAIL PROTECTED]; Stig Sæther Bakken [EMAIL PROTECTED] Cc: [EMAIL PROTECTED]; [EMAIL PROTECTED] Sent: Sunday, September 30, 2001 11:02 PM Subject: [PHP-DEV] Re: [Zend Engine 2] Re: [PHP-DEV] namespaces ambiguity Well the difference is that C++ can figure out what to do at compile-time. I don't think we can which means that it would put more logic into run-time which is a bad thing IMO (especially for something new like this). Or can you think of a way to differ between these at compile-time? Andi At 09:56 PM 9/30/2001 +0200, Zeev Suraski wrote: :: is taken, but why not do it the C++ way?

I think I've thought of an ambiguity (with constants) which makes me wonder how feasible the proposed syntax is. Consider the following expression: $test?FOO:BAR:BARBARA Would this mean that the person meant $test?(FOO):(BAR:BARBARA) or $test?(FOO:BAR):BARBARA? Okay, is there another character we can use? Doesn't look that way. Maybe we need to use two characters then? Since both :: and - are taken, // is the best suggestion I can come up with. - Stig -- Stig Sæther Bakken [EMAIL PROTECTED] Fast Search Transfer ASA, Trondheim, Norway -- PHP Development Mailing List http://www.php.net/ To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED] -- PHP Development Mailing List http://www.php.net/ To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
