#phpwishlist not_null() not_string() not_callable() not_a() ... Yeah, I realize that `!` exists, but (a) fluent, and (b) can be called by name where a callable would be expected. Thoughts?
Related: `isset` should be a function, not a language construct. 🔥
I’d love currying and functions as values so you could write: not(is_null) and use that. In lieu of that tho: yeah these fns would be nice.
Yeah, but I also want to be able to do: $foo = array_filter($bar, 'not_null');
functions.php: function not_null($foo) { return !is_null($foo); } Why does this have to be on the language level?
One less external dependency for universal utility.
