These lines were just a basic idea...of course I have to fill the array...
string[] a=new string[2];
a[0]="A";
a[1]="B";
my idea was to create a list class to store something in it...
class List(T)
{
T[] arr;
// ctors and such
void opIndexAssign(T e,int i)
{
arr[i]=e; // And here it throws the exception that arr is not mutable...
}
}
