Allow a 'final virtual' classes to be declared.
...
The build was successful.
Virtual final classes are helpful in the case someone is wrapping common functions that are static, but the common class itself cannot be instantiated.

Assume private visibility for all class members by default.
...
The build was successful.
In most (all?) modern OOP languages class members visibility is assumed to be private and programmer has to consciously set it to public or protected. PHP has the different approach what can cause a security flaws in written scripts. AerScript will not follow this way, as it seems to be conceptually broken.

In AerScript, there are no such language constructs, that have syntax similiar to functions. If so, it is just a builtin function.

Make constant declarations local.
...
The build was successful.
There are several changes in this commit:
* first of all constants declared by 'const' statement should be local (declared in current scope / frame),
* constants are declared by using OP_DECLARE instruction,
* OP_LOADC browses both global and local constants container,
* PH7_VmRegisterConstant() allows both global and local declarations.
Since this commit, there are 3 kinds of constants:
1) global
2) local (in loop, closure, method)
3) class members.
Actually there is no way to declare a global constant except the built-in constants.

The build was successful.
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.

Do not allow 'continue' statement in a switch case.

Important rule while using continue statement is that, We can use continue
statement only within the loops. Switch case is conditional block not a loop
so we cannot execute the continue statement inside switch.
