Allow a 'final virtual' classes to be declared.
...
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.
...
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.

Remove unused compiler function - PH7_CompileLangConstruct().
...
In AerScript, there are no such language constructs, that have syntax similiar to functions. If so, it is just a builtin function.

Implement 'define' statement for defining constants globally.
2019-05-04 17:08:09 +02:00
ab8bf48485
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.

Always emit OP_JMPLFE as goto can be used inside a loop and frame has to be left.

Refactor foreach() loop.
...
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.
