In AerScript, the foreach() loop is syntatically more similiar to C#, than PHP. However the optional '$key => $value' construct is still available, because arrays in AerScript are still a hashmaps.

This function is useless in Aer, as it is fully OOP language and thus disallows functions declaration.

AerScript is fully OOP language and supports exceptions that can be thrown at any time.

Interpreter will abort script execution on first error found.

Thus code placed below will never get executed and is completely useless.

After last change, AerScript does not pass arrays as reference, so there is no chance to get this function return true, unless you pass array as reference.

AerScript makes a copy of all arrays, except a situation when array is passed by reference. Thanks to that this ugly hack called an extension, introduced by Symisc can be removed.

This function needs to store the next index. Otherwise it will start to count from beginning, duplicating existing keys.

And if we managed to insert a boolean value to an array of chars, this means we have a bug somewhere.
