This means that the following code is an error: function foo(int $a) {} foo(‘8493284029384029384028409304249230894’); This is actually a level of safety you couldn’t get with any other proposal. If you explicitly cast with (int) it will silently saturate/cap the integer (data is lost), and zend_parse_parameters will silently saturate or truncate (depending on the function). This is consistent with passing a float. Were I to do the following, it was already an error in the proposal: function foo(int $a) {} foo(8493284029384029384028409304249230894.0); -- Andrea Faulds http://ajf.me/
