Implement the implicit 'auto' type.
...
An implicitly typed local variable is strongly typed just as if it had been declared the type, but the compiler determines the type. The following two declarations of $i are functionally equivalent:
int $i = 10; // Explicitly typed.
auto $i = 10; // Implicitly typed.

Assume private visibility for all class members by default.
...
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.

Make constant declarations local.
...
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.

statement only within the loops. Switch case is conditional block not a loop
