Thanks for the detailed analysis, kcott. I am using 5.34 so adding in use v5.34; has allowed the construct to work for me. use feature 'postderef_qq'; also works.

However, the version-dependent nature of all of this combined with the paucity of documentation and the arcane error message received has only served to reinforce my decision to avoid postfix dereferencing in general.
