You might be used to other language's scoping, but
this is the way PHP works.

Named function cannot do this, but anyway
function FUNC($a, $b, $c) uses ($d, $e, $f) {}
is like
function FUNC($a, $b, $c) { global $d, $e, $f; }

I would rather have this.
function FUNC($a, $b, $c) uses ($d, $e, $f) {}
Then it would be consistent with anonymous function.

There are methods, so we should be careful though.

Regards,
