# Welcome to my "arel gist"!
## It started hacky, then as an example, but we want it cleaner.
# ActiveRecord
## This is an ORM: you call Ruby methods and get Ruby objects, it makes SQL and object instantiations for you.
## It's Rails' default, but there are alternatives: https://github.com/Sdogruyol/awesome-ruby#orm

;; A quick and dirty tree shaker for SBCL. Basically, it destroys the
;; package system and does a gc before saving the lisp image. Gives
;; about a 40% reduction in image size on a basic hello world test.
;; Would like to hear how it works on larger projects.
