My question is not so much about implementation it is about language. I
have noticed quite a few times now that PHP developers use the word
closure when I would prefer lambda.

This is not entirely correct, you are right. There's a difference
between anonymous function and closure, though in practice in PHP
anonymous functions are closures (though some of them are rather trivial
ones with no variables to close over) and that's now the only way to
do closure in PHP (i.e.

You probably don't use closures, right?

Oh, yes, the question:
Wouldn't you agree that it is better for PHP to use the word closure as
it is being used in the JavaScript community?
There's a pretty big difference between how PHP implements closures and how
