I converting a peice of C source to Perl. The C has the following construct 

 switch(len) {
    case 11: c+=((unsigned int)k[10]<<24);
    case 10: c+=((unsigned int)k[9]<<16);
    case 9 : c+=((unsigned int)k[8]<<8);
    case 8 : b+=((unsigned int)k[7]<<24);
    case 7 : b+=((unsigned int)k[6]<<16);
    case 6 : b+=((unsigned int)k[5]<<8);
    case 5 : b+=k[4];
    case 4 : a+=((unsigned int)k[3]<<24);
    case 3 : a+=((unsigned int)k[2]<<16);
    case 2 : a+=((unsigned int)k[1]<<8);
    case 1 : a+=k[0];
     /* case 0: nothing left to add */
}

I've elected (for now) to translate this as 

    goto 'LAST'.$len;
    LAST11: $c+= $k[10] <<24;
    LAST10: $c+= $k[9]  <<16;
    LAST9:  $c+= $k[8]  <<8;
    LAST8:  $b+= $k[7]  <<24;
    LAST7:  $b+= $k[6]  <<16;
    LAST6:  $b+= $k[5]  <<8;
    LAST5:  $b+= $k[4];
    LAST4:  $a+= $k[3]  <<24;
    LAST3:  $a+= $k[2]  <<16;
    LAST2:  $a+= $k[1]  <<8;
    LAST1:  $a+= $k[0];
    LAST0:

Any offers for a better translation?

Examine what is said, not who speaks.

The 7th Rule of perl club is -- pearl clubs are easily damaged. Use a diamond club instead.
