A good way to get to know splice better is to re-implement push, pop, unshift and shift with it.

Uhm, or you could just read the docs :-)
A good way to get to know substr better is to create push/pop/unshift/shift functions for strings.
D:\Development>perldoc -f splice
The following equivalences hold (assuming "$[ == 0"):
$a[$x] = $y splice(@a,$x,1,$y)
Well.... Once you know how to implement splice using susbtr you dont need to implement push/pop/unshift or shift, but its true it might be a good exercise.
Personally would suggest taking that thought a step further and reimplement Tie::CharArray, by the time you are done if you dont understand Tie's, Array implementation, Splice Implementation and Substr implementation then I would say theres something very wrong... (either with the individual or the code ;-) Oh and it probably is a good idea because you can use the CPAN module for a proper code comparison and review afterward.
Thats what I did to learn Tie the first time anyway... :-)

Writing a good benchmark isnt as easy as it might look.
