I think there is a misunderstanding here. Inclusions with two arguments are currently not allowed, yes. The point is that adding such a second argument would make the grammar ambiguous. E.g, consider this: func(include 'foo', $someThing); Currently this is interpreted as the return value of 'foo' and the variable $someThing being passed to func. If you add a second argument it's unclear what this does. Is this a two-argument include? I.e. should it be interpreted as func((include 'foo', $someThing)); Or is this a one-argument include and should be interpreted as func((include 'foo'), $someThing); In my eyes such an ambiguity renders any proposal to add another argument to include completely unacceptable. The only option is to add a dedicated syntax for it like include 'foo' as $flags; Nikita -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
