Re: Re: Re: hash 2 array ?

Wouldn't this kill any chance of using leading digits in keys ({ '34' => 'thirty four' })? And take a significant runtime hit to pack and unpack accordingly?

Tie::IxHash is already done. Does this not serve the purposes required?

Eh... I added a packed ordinal number to the value of each hash entry. Doesn't have anything to do with keys. And yes, you will have a runtime hit, but only if you need to sort (when you need the ordinal number) and/or obtain the (real) value of the hash entry. Again, my solution optimizes for memory usage. Not CPU. YMMV. With regards to Tie::IxHash: that's a fine module, but may be doing (a lot) more than you want. And don't forget the inherit CPU hit for using a tied hash. Finally, TIMTOWTDI. ;-) Liz	[reply]
