Ok, let me try again.
Yeah, I know the C++ standard don't allow that semi-colon there... but both GCC
and CLang won't complain if you add it there, and GCC accepts it even in Java.
I've seem lots of code where people put it there, and I always get a little
frustrated when using PHP because I'm used on adding it (without even
noticing), and my code keeps failing because of that.
Wouldn't hurt to make the parser simply ignore it. =P
Know, about the multiple returns...
Ruby and Lua let you return multiple values... why won't PHP allow you?
Usually it's best to return an array, I totally agree, but I was working on a
Lisp-like parser for PHP yesterday and it would really help me for two
expressions to be returned from a single function, since I'm using tail
recursion and on a few cases I needed to add two values to an array.
You guys will tell me to use something like flatten(), probably
RecursiveArrayIterator or stuff, but... for future implementations, that
multiple return would help. =P
Better?

Hi,
I'm currently interested in two features I'd like to see in PHP; how do I
proceed to request/propose them? I'd be glad to help implementing them as
well, if necessary.
One of them is really simple, but would be helpful to people with different
coding styles
class Test {
public function blabla() {
// ...
} // the interpreter fails if there
// is a semicolon here, although
// some c++ programmers may be used
// to add it
That one is wrong in C++, too. Unless you're confusing function
declarition with function definitions.
class CPPClass {
void some_declaration();
void some_definition_of_an_inline_function() {
return;
} // No ; here
}
};
Well, people should be aware of the language they are using ...
And the other one would be multiple return values
function multi() {
return 10, 20;
Use
return [10, 20];
which exists and returns an array. This is clear and quite easy to read.
};
function sum($a, $b) {
return $a + $b;
};
echo sum(multi()); // echoes 30
This becomes confusing when reading.
echo array_sum(multi()); // :)
