RE: [PHP-DEV] FW: Functionality request/proposal
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?

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 ...

Use
return [10, 20];
which exists and returns an array. This is clear and quite easy to read.

This becomes confusing when reading.
echo array_sum(multi()); // :)
