Semicolons were invented not by stupid people...

It's interesting how would you write without semicolons the following:

from($categories)
    ->orderBy('$v["name"]')
    ->groupJoin(
        from($products)
            ->where('$v["quantity"] > 0')
            ->orderByDescending('$v["quantity"]')
            ->thenBy('$v["name"]'),
        '$v["id"]', '$v["catId"]', 'array("name" => $v["name"], "products" => $e)'
    );

???

I would try these rules:
do ";" if line ends with "\n" and
- next token is not "->" and not an operator (-+%...)
- "(", "'", "\"" are currently not open on stack and
- previous token is not an operator and
- start child stack if "function" token comes and
- not inside "function|if|while|switch|for|foreach () {"

e.g.
$test = [
  [],
  function ()
  { // do ";"
    return "test" // do ";"
  },
] // do ";"

for must remain:
  for ($i=0;
  $i<10;
  $i++) {}

small correction:
- "(", "'", "\"", "[" are currently not open on stack and

Wow, complicated. I think we will stick with the simple ';' to end an expression.
