I saw a proposal connected to match about a year ago that included type
based matching, something like:
match ($var) {
true => 'true',
false => 'false',
instanceof int => "int($var)",
instanceof string => "\"$var\"",
instanceof object => get_class($var),
instanceof DateTimeInterface => $var->getTimestamp(),
default => rtrim(print_r($var, true)),
};
That might satisfy at least one of the use cases in a general way.

Yeah. Within the context of this featurette, that's something we should
include in the proposal. If you're doing a match(true/false/other-literal)
(explicitly or implicitly) then your cases should be commensurately more
well constrainted.
