Re: one-line function definitions

Transliterated (counting cultural differences), it owuld become:

def antology_title (data, prefix); get_field(data, prefix,
'ANTHOLOGY-TITLE'); end

But more importantly, it probably wouldn't exist, since ruby culture
sees explicit getters/setters as repeating yourself and finds
meta-solutions, a-la attr_accessor or def_delegator.
