Hi Seifeddine,
I understand the reasoning behind freeing up the `list` keyword and
having a canonical way to destructure an array. However, I would argue
that the scale of this BC break far outweighs the benefits.
A quick GitHub code search shows 7 million[^1] hits for "list(" in PHP
files. If we deprecate and eventually drop `list()` in PHP 9, we can
safely assume that a large portion of existing code will fail to
compile in PHP 9.
Furthermore, the documentation for `list()` offers no hint that `[]`
is preferred over `list()`, and I would also argue that there is no
reason to prefer one over the other. Code-style guides can dictate a
project's or library's conventions, but we should take a more
conservative approach if we really have a strong technical reason to
prefer one syntax over another.
Based on the RFC text, aside from freeing up the `list` keyword for
potential future use, I do not see a sufficiently strong technical
reason to deprecate `list()`.
Thank you.
