    OK. I need to sort a list and I have the following code

            @L=(35,10,0,27,100,-4);
            sub numeric { $A <=> $b; }
            @L=sort numeric @L;

    The only reference I have is an ancient Oreilly book on Perl 4.
    does sort() actually sort the operand list or only return a sorted list?
    Is it safe to use the source operand as the return value of sort() as well?
