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 =3D> $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?
