Primarily a class system as a first class citizen of the language, with uniform object syntax, without sigils or other syntactic contortions. Being able to pass around open file handles without having to look up 5 kinds of punctuation. Being able to build up complex data structures without having to use explicit references, where something completely different would auto-vivify itself if I used the wrong sigil.
