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?
If it's an problem parsing config, it would be best practice to
throw an exception or error, but for future reference, if you
want to terminate execution use Runtime.terminate from
core.runtime, followed by C's exit from core.stdc.stdlib.
Runtime. terminate will do cleanup and allow the program to
shutdown properly
