PHP

Named arguments allow passing arguments to a function based on the parameter name, rather than the parameter position. This makes the meaning of the argument self-documenting, makes the arguments order-independent, and allows skipping default values arbitrarily.

Another RFC proposed for PHP 8. Not sure exactly how I feel about this one yet. I like the idea but Jeremy also pointed out that then params become part of the public API. Need to think about this one some more. -Chrispian

Short circuiting refers to skipping the evaluation of an expression based on some given condition. Two common examples are the operators && and ||. There are three ways the nullsafe operator ?-> could implement short circuiting. We’ll look at the same code snippet for every option.

I like this idea. I usually don't like things that makes code less easy to understand and favor being more verbose. In this case I think this one actually makes it easier to read and might make it a little easier to avoid making silly mistakes. -Chrispian
