Hi Stefan,
The point was not about array filtering or LINQ or any of that. It was about
the plausibility of using a shorthand for closures.
Instead of this.....
array_filter($source, function($x){ return $x < 5; });
Being able to do this..... (or something like it).
array_filter($source, $x => $x < 5);
This would provide a much more friendly way of using callbacks. Lambdas have
great uses, but I feel like they are underutilized in PHP. C#, for example, has
made excellent use of a lambda-friendly syntax like the one above, and Java is
planning something similar (for Java 8, I believe).

Hi,
well, for your examples: Why not just array_filter() with an appropriate
callback? Should handle it like you describe plinq does it, right?
