For example: try-catch : %try_block, <BLDSyntaxException:ExceptionType>, %catch_block ;
It need: ExceptionType struct, release exit program when throwed exception.
Also we need create ThrowExpression: throw : <ValueException:ExceptionType>;

From this moment You can use settings.
For example code in build-file:
settings = example.xml
Code in example.xml:

<!--example-->
<settings>
    <project>
          <name>Example</name>
          <version>1.0.0</version>
          <entrypoint>#main</entrypoint>
    </project>
</settings>

And to our project add constants name = "Example" version = new Version(1, 0, 0). Else when run project will run function main.

It`s the simplest example of using settings.

Variables, functions, classes don`t push to stack.

nine = int PUBLIC get [
    Return : <9:int>;
]
main {
    Plus : @nine ;
}

This code throw exception that Variable by name nine not found

if variable or other property is 'private' and call in main script throw SecurityException

Add the ability to make labels and go to them

Add the ability to add frameworks (libraries for vm). Else add expression '_loads' and documentation for creating frameworks.

You can create destructors but cannot use becouse while it`s bug

Add base classes: byte, int, short, long, float, double, char, string, Type, Enum, Link, Func, Collection, Block, Array and configure them.
