            x = 100;
        }

        c.call()
        println x;  
    }

I think it is important that Groovypp is Groovy Plus Plus, which means it just 
add functions to groovy not break it.

If Groovypp is not compatible with groovy, it will makes it an obsolete branch.

The example code works well in groovy.
