Hi Dave,
Regarding the =& open issue in the RFC, I don't think the =& syntax
makes sense to me. The thing on the right-hand side of a list()
assignment is the array, not its values. It makes no difference for the
purposes of assigning from its values if the array is a reference or
not, so I'd expect the & here to do nothing at all. So, having the &s
only on the left-hand side makes more sense to me. I think supporting =&
would be a potential source of confusion.
On a different note, the RFC doesn't mention support for the shorthand
list() syntax introduced in 7.1 (i.e. `[&$a, &$b, &$c] = $arr;`). Since
it shares its implementation with list(), I assume it is indeed
supported, but you should probably explicitly whether or not it is, for
clarity's sake.
Thanks for your work on this! I'm glad to see it revived. :)
