I simplified the example, cdc does more than just a change the directory. `cdc -t name` changes to the directory and attaches to the tmux session of the same name if it exists, and if it doesn't, sets up my tmux layout for development.

whilst reading your above comment i wondered why you chose not to use environment variables instead. e.g.:
$ export cdc_stuff='/Users/me/src/project_stuff'
$ cd $cdc_stuff
in the event you're looking for alternatives, perhaps porting your code to (e.g.) ruby could work.
just in case, here's the isbn number of a book called, 'Build Awesome Command-Line Applications in Ruby 2,' from the pragmatic bookshelf: 978-1-93778-575-8
Admittedly for the description given, it does sound like CDPATH would work. But I'm going to assume there's a reason, and functions that change the current working directory are the perfect example of functions that can not be run in a subshell, so will have to be rewritten to fish, which is what the author was providing.
