Yeah, Serhiy said basically the same thing: it's doable, but complex
without builtin support for positional-only arguments.
I dislike subtle differences between C and Python, and positional-only
is a major difference since it has a very visible effect on the API.
After having used PHP for years, I really enjoyed Python keyword
arguments and default values. I was very happy to not have to
"reimplement" the "keyword arguments with default values" feature in
each function (*).
Basically, I would like the same thing for positional-only arguments :-)
(*) Example (found on the Internet) of PHP code pattern for keywords, enjoy ;-)
function doSomething($arguments = array()) {
// set defaults
$arguments = array_merge(array(
"argument" => "default value",
), $arguments);
var_dump($arguments);
}
