I think compact() is a good function for transferring variables from one point to another, but I would think about making improvements as it is confusing (uses the variable name, rather than the variable itself). Regarding the bug, if we use an array it should work perfectly: $x = 123; (fn() => [ 'x' => $x ])(); https://3v4l.org/ov7TM Would it be possible to automatically convert compact() to an array at runtime? So I imagine that any necessary optimization can take place directly over the resulting array, rather than the compact itself.
