For me Perl is (awk|sh)++. It's a great example of the Unix philosphy, which is, among other things, evolution based on practical experience rather than top down theoretical design.
For me perl5 is lexical scoping, closures, map/grep/reduce, and an OO model that steals the best of python (ignoring ruby's crippled OO which involved failing to steal from smalltalk properly) and then adds a first class attribute system so you can declare attributes once and not need to re-type the names to get a working constructor.
ES6 isn't bad, mind - with 'use strict' and 'let' it's close to a usable perl5 apart from the fact that its errors are runtime instead of compile time (typescript helps there of course) and the OO is still relatively limited, but I have some ideas using decorators that should bring the best of perl5 OO to javascript since I've been unable to convince anybody else to steal our features already
People often complain that I write lisp in everything.
I mostly consider this a feature.
