Regarding the patterns, is there a way to declare and reuse the patterns? Assign
it to a variable and use it as “is $pattern” or something like that. Maybe as a
separate class “$pattern->match($var)”.
There is an annex document on more speculative extensions linked in the
RFC that mentions this:
https://github.com/Crell/php-rfcs/blob/master/pattern-matching/future.md
I was going to raise the thought of using these patterns to constrain
function parameters (despite the heavy overlap of "$var is type" and
"type $var"), but found that already included in the annex as well.
