How catch any error in Dlang like Python tray-except?
It is very useful when making tests. But only who came from 
interpreted languages can understand.

Exemple:

import std;

void main()
{       
        try {
                writelnX("try function that not exist");
        } catch (Throwable e)
        {
                writeln("Error: %s".format(e.msg));
        }
}
