Ah, I guess I'd missed that part in the docs for the Hash::Case::Lower
module. Is it safe
to 'delete $thawed' after I tie the hash so I don't have an extra copy
of the hash
floating around?
Try and see. A look at the source suggests there isn't a problem doing it, if there is I would think it is an implementation bug. I assume by "delete" you mean allow the variable to go out of scope or otherwise get garbage collected, as opposed to 'delete' as in -f.
Correct.
You may also want to consider that nested hashes (if my understanding
and glance at the code are correct) are not necessarily lower case. This might be either a suggested improvement, or even a new subclass of
Tie::Hash, aka Tie::Hash::LowerDeep or similar, essentially you would
end up with a nested call to tieing any internal hash refs.
I'd realized that. I don't need the nested hashes to be lower case, so it is not an issue.
