Hi, I must say that the prospect of yet more new syntax is scary. It really looks like Perl, and I wouldn't have the slightest clue what it meant if I'd missed the release notes. I've pined for something like coalesce($_GET['foo'], $defaults['foo'], 42) for years, and I think that style is far more in keeping with the PHP ethos, and far more readily understandable than this suggested new syntax. If I've missed some argument against this then please correct me. Regards, Arpad -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
