Hi,
One issue to resolve is how to interpret:
```php
$x = match {
preg_match('/a/', 'a') => "will it be matched ..."
, default => "... or not?"
};
```
knowing that preg_match(...) never returns `true`, but one of `0`, `1` or
`false`. More generally, how to deal with truthy-but-not-true values.
I see three options:
(a) check for strict equality with `true` (i.e. make `match {}` equivalent to
match(true) {}`). The `preg_match(...)` branch will never be taken;
(b) check for truthy values. The `preg_match(...)` branch will be taken if the
condition evaluates to 1;
(c) mandate a boolean: The `preg_match(...)` branch will throw a runtime error
if the condition evaluates to 0 or 1;
Personnally, I am against option (a) as it is confusing and would be a source
of bugs.
