Update eshell aliases
I should replace this file later with some Elisp code in the user init
to read aliases from Fish abbreviations.
Something good would be to try to write some Elisp code to emulate Fish
abbreviations, but I have to find what hook or function is called when a
new character is entered in the shell that triggers autocompletion. Code
in this package might help:

This commit adds two new snippets for Rust, one for an easier way to
write a `println' macro than the default one, and another one for
writing more easily new `new' functions for Rust structs.
It also adds the `common-lisp' layer in Emacs so I can test StumpWM.
