* Regex pattern
This one is interesting as well ... but I would expect native regex
syntax first before introducing it as part of a different RFC. Similar
as generics.
Named capture groups are already part of regex syntax, just not often used.
The example is not introducing anything new there. (Although Ilija tells me it
may be hard to implement, so it may get postponed anyway. TBD.)
I think what Marc means is that it's weird to see the regex syntax
outside of a quoted string, since we don't currently have that syntax
defined in PHP.
It's not even clear what the constraints of that syntax would be; for
instance, this is valid PHP:
$result = preg_match(subject: $string, pattern: "#
(int|string)
/*(.*/)
#xi");
But I'm guessing it would be a challenge to parse this:
$result = $string is #
(int|string)
/*(.*/)
#xi;
The simple answer is probably to use a more limited syntax, but defining
that syntax probably deserves its own discussion.
