How I Wish Racket Was First Explained To Me

I've been taking a compilers class this semester from Matt Might, which has been a great experience. Amongst the most challenging/interesting aspects of the course has been taming Racket, a Scheme-y/LISP-y language (I'll leave it at that).

Having never used anything functional/LISP-y in my days, this was a brand new experience. On the whole, it was good, but here's how I wish my first introduction to the language had gone as it would have set me on the right foot. While I'm focusing on Racket here, I imagine this same thing applies to LISP/Scheme and its derivatives.

Code vs. Data

I read everywhere that, "In Racket, code and data are the same thing." That sentence alone was useless to me, and it took a number of weeks before I "got it." Perhaps this explanation may have been more helpful:

Sequel.migration do
  up do
    run 'CREATE EXTENSION "uuid-ossp"'

    create_table :products do
      column :id, :uuid, :default => Sequel.function(:uuid_generate_v4), :primary_key => true
    end
  end
end

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.
