Bug report

PHPStan seems to incorrectly assume that string conversions cannot throw exceptions. While this used to be the case (although there were obscure workarounds), this is now officially supported: https://wiki.php.net/rfc/tostring_exceptions.

Consider the program below:

try {
  (string) $myVariable;
} catch (Exception) {
  // Reported as dead catch, even though the `__toString()` method
  // in `$myVariable` might throw an exception.
}
