Isn't understood by who? Used wrong by who? Are we talking about people using a feature, that doesn't exist yet in PHP, the wrong way and arguing that there is an apparent lack of understanding of this non-existent features among the user-base? I'm sorry, I really don't follow this train of thought. > And I think, that it is too easy to oversee that it is not a "normal" > PHP-function, because the "yield" is normaly in the middle of the code > and "return" at the end. > The only thing that's not normal here is the flow of control being passed back and forth between the generator and the function > Both couldn't be changed.

If it's a function definition it clearly should be called a function in order to remain inline with the existing PHP code out there. Otherwise you're adding more confusion. The fact that the function contains a "yield" shouldn't change the fact that it's still a function. I agree it behaves differently, but the same could be argued about functions that call other functions or even functions that call themselves. The flow of control there isn't always obvious from static code analysis, but that's what the runtime environment is there to aid the developer with. How is changing the name going to aid the developer's understanding of generators any better? I doubt this adds any real value here aside from pointing out the already obvious "this function contains a yield". > > ...

Do you have that? > 20 years experience in PHP? No, I believe it only ever appeared publicly about 17 years ago. 20 years experience with developers that have problems? Yes, there's no shortage of them. -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
