Would you please reply if you know of a module fitting the below use case? I have searched Google and MetaCPAN and can't find one --- I'm pretty sure I'm missing something obvious in my search terms!

I am looking for a 5.14-compatible module that will, given a list of strings, permit me to test for case-insensitive membership in the list of strings, and to move from one item to the next. I would like to do things like:

$set = Some::Module->new(qw(foo bar bat));
$set->contains('foo');   # true
$set->contains('FOO');   # true
$set->after('foo')       # 'bar'
$set->is_last('bar')     # false
$set->is_last('bat')     # true

I already have an implementation based on an array (here et seq.). However, it is very clumsy and requires me to lc()/fc() everywhere to get case-insensitivity. Before I spend the time making a new module, I'd like to see if there already is one. Thanks for your help with this!
