That was Stas's original, original proposal way back when. I argued then for having "default" as a placeholder, and still would today — in the case where a function with, say, ten optional parameters[0] is being called and eight of them should be the default, I think it's a bit rough for somebody inheriting that code to have to count commas. Having a token increases readability, IMO, and costs us nothing except a few keystrokes, which isn't going to break the camel's back in a language that requires "function" each time you declare a function. Adam [0] Yes, that's probably poor API design. You and I both know someone will do it, though. :) -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
