in thread what would you like to see in perl5.12?

The only script-visible changes would be the module you include to say you want sorted hashes
It'd make more sense to me to have a :btree attribute on the hash declaration (does that mean lexical hashes only? maybe). Would the attribute take an optional comparison function?
and the function it exports so you 'seek' the each operator.
I'd put that in Hash::Util. Is that seek to a particular key value, or seek to key N?

    It'd seek to a particular key value. There are certainly trees that would also allow seeking to a particular index. I don't care whether there is a way to override the default comparison function (just cmp).

    Yes, using an attribute for this would be fine.

    Update: s/<=>/cmp/.
