 Ruby looks for the file in the directories listed in `$LOAD_PATH`. That is, Ruby
-iterates over all its directories and for each one of them checks whether they
-have a file called "erb.rb", or "erb.so", or "erb.o", or "erb.dll". If it finds
-any of them, the interpreter loads it and ends the search. Otherwise, it tries
-again in the next directory of the list. If the list gets exhausted, `LoadError`
-is raised.

 We are going to cover how constant autoloading works in more detail later, but

-it, and have `Post` defined as a side-effect.
