I'm trying to use Test::More and Test::Deep to compare two complex data structures (nested objects). Ideally, I would use cmp_deeply and pass it both data structures, but do a lower (or upper) case on all the values so the comparison would be case insensitive. Something like
return cmp_deeply( lc($Expected)
, "This is my case insensitive comparison"
Am I missing something obvious here? I don't want to change the actual data in the structures. I also don't want to just stringify it because I want the diagnostics that come with Test::More to show what values actually fail.
