And I am suggesting that a block-enclose expression should not be limited to
expressions only, but instead be able to use statements in the future. Using
commas ensures we can never go that route.

You have a point.
But that use-case is not a block, it is an obscure short-hand syntax for which
nothing else in PHP is similar. I would not expect we should use it as a model
unless it were for a very similiar thing.

I did not state it before because I did not want to spend time on things I felt
were irrelevant but the fact another language uses syntax does not make it
appropriate for PHP. What makes it appropriate for PHP is "feel", consistency,
and how sigils are already being used, and how they might be used in the future.
But I am not saying you do not look to other language for inspiration. What I
am saying is you cannot look to other languages for validation, at least not in
a vacuum.

Ok, so let's look at a scenario. Will we be able to do this in the future, if
we decide to allow multiple expressions to result in a final value?
$y = switch ($x) {
case 1 => $arr = get_array(), array_pop($arr),
case -1 => $arr = get_array(), array_unshift($arr),
default => null,
};
What if in the future PHP implements variadic syntax for assigning to arrays,
e.g. $var = 1,2,3 where $var could satisfy a $variadic parameter set of
parameters w/o requiring `...`? If PHP embraces that — note GoLang has
something similar — then will comma syntax allow for it with hacky use of
parentheses?
$y = switch ($x) {
case 1 => $var = 1,2,3, $var[1],
case -1 => $var = 9,8,7, $var[1],
default => null,
};

Are you saying it is literally impossible given the current engine, or just
that it has not been done with `break`, `continue` or `goto`?

No. I would assume the other, so I have to assume I would not be the only one.

Your response makes me think you are responding in anger? I am not arguing in
anger myself, so I hope that I am not causing you to reply in anger? I am
merely asking posing technical challenges in hopes to ensure that PHP is the
best it can be. I assume we all want that?

P.S. And I do not mean my input is needed for PHP to be the best it can be but
only that having different opinions debated in a reasoned manner tends to make
for a better outcome.
