I agree that the `fn` keyword isn’t really necessary. I’ve never quite
understood how arrow functions with implied returns etc are supposed to make
for *more* readable code, but if they’re going to be part of the language
please at least keep some consistency with regular closures.
In the case that regular closures got auto-capture, would a `use($foo, $bar,
$baz)` segment on a closure still be honoured (i.e. disable auto-capture), and
would it have any impact (positive or negative) on performance/memory usage?
After several years of JS closure ‘fun’ I kind of like that with PHP you only
inherit the variables you explicitly `use()` in closures.
Cheers
Stephen
