I wish they implemented them like in JS without the unnecessary fn().

  That would give syntactic ambiguity, since the => operator is also used to separate keys and values in array notation.

    Fair, but seems inconsistent to have `fn` instead of `function` like we use for anonymous functions - unless `fn` acts like an alias to `function` now (which doesn't sound like is the case) which wouldn't be as ambiguous for the compiler to figure out
  • bufferoverflow 7y ago
    I don't think there's an ambiguity, since the key-value application of that operator only happens inside the array definition or when you do foreach ($x as $k => $v) {}.

      There is ambiguity. This was specifically mentioned in the RFC for the feature: https://wiki.php.net/rfc/arrow_functions_v2#syntax https://wiki.php.net/rfc/arrow_functions_v2#syntax

      It does if you're trying to make an array of anonymous functions...
