After over a decade of professional experience using bash, in 2013 I've started developing Next Generation Shell. I'm still on it. Probably not the size of project that you were looking for :) tldr: better programming language (syntax, error handling, data structures - full blown but still domain specific programming language), better interactive mode (at least that's what I think).
