[challenge] Linker surgery

[IgorStepanov]

Do this table linked, if you remove all functions, which use it?
It not, you can try the next method (Another hack).

extern(C) immutable int[] table_ = [1,2,3]; //table_.mangleof ==
"table_";

int foo()
{
        pragma(mangle, "table_") extern immutable int[] table;
        return table[1];
}

In this hack we "fooling" the compiler. We say, that "table_"
doesn't used in foo(). foo() use another extern array "table"
with overrided mangle (new feature)
