I have got class Config with method parseconfig. I need

void parseconfig()

catch(Exception e)
{
writeln(e.msg);
// throw any exception here
}
}
But my main.d also have try catch block and parseconfig()
calls inside it. The problem that wen exception rise I do not
know how to terminate app. Exception simply print on screen
and app is continue.
void main()
{
try
{
parseconfig(); // exception was already handled inside:
void parseconfig()
}
}
What is the best practice to stop app?
Since C's "exit" function is not liked, best thing you can do
is to throw an Error when you want to close the program. You
are not supposed to catch Errors. So, it eventually will stop
the currently running thread.
but if I throw exception it's handled in instance of class Config
and it's not go to main...
And what the reason to not add support of C's "exit"?
