do expression about compiler HOT 3 CLOSED

Can we emit using goto? Strategy would be to:

• Add a generated label after the code
• Replace return with assignment and goto

// Example 2
foreach ($this->list as $element) {
  if ($search === $element) { $found= true; goto __l0; }
}
{ $found= false; goto __l0; } // Maybe optimize this last line to omit the goto
__l0:

Unclear how this would work for example 1 though.

Still don't have a good idea, closing for now.

Sometimes it would be nice to have a code block inside an expression, like this:

public function f(string $key) {
  return $this->cache[$key] ??= {
    // Calculate a value for $key.
    [...]
    return $value;
  };
}
