# /u/zaclacgit on Reddit posted a topic the other day asking for thoughts on his exercise of 
# recreating some basic enumerable methods. I gave him some tips on refactoring one method in particular
# and a few days later, he asked me to elaborate. I thought the easiest way might be to go through each
# step of the refactor and I'd get a nice blog post out of it in the process.

# To use this, start by commenting out each `my_inject` definition except the first. As you encounter
# new ones, uncomment them. Save this file as `refactor.rb` in the folder of your choice, ensure you have
# the rspec gem installed and run `rspec refactor.rb` from CLI to execute.

# Before we write a line of code, we're going to write specs based off of the simple comparisons
