import std.stdio;
class Exception
{
    char[] Exception;
}
void caller()
{
    int count=0;
    void func(lazy char [] errormessage)  // if it can be a nested func inside
the caller would be nice
    {
        count++;
        if (count<3)
        {
            throw new Exception(errormessage);
        }
    }

    try 
    { 
        delete_directory("/home/someuser") ;
    } 
    catch 
    {
    }; 
}

void delete_directory(char [] dirname) 
{ 
//    caller.func("hurray");
//    caller.func("hurray");
//    caller.func("hurray");
}

void main()
{
    caller();
}


and the example code here is trying to interact with the try block owner
i hope compiler would be able to generate the func in the example.

like we have code 

import std.stdio;
class Exception
{
        char[] Exception;
}
void caller()
{
        int count=0;

        try 
        { 
                delete_directory("/home/someuser") ;
        } 
        catch 
        {
                count++;
                if (count<3)
                {
                        continue;     // i want that to continue the point
where throw the exception
                }
        }; 
}

void delete_directory(char [] dirname) 
{ 
        throw new Exception("File1");    // maybe we can add a keyword like
action, to let the try block to determine how to deal with the action, then we
won't affect the exception we have now;
        throw new Exception("File2");
        throw new Exception("File3");
//      caller.func("hurray");
//      caller.func("hurray");
//      caller.func("hurray");
}

void main()
{
        caller();
}
