Another type of mistake is when what you typed in makes sense to Lua when you typed it in, but when it's time for code to be actually run, something wrong happens. For example, you asked Lua to eecho("hey!") - this is valid, you typed it in right, but there is one problem - eecho doesn't exist. So when you run the alias, nothing actually happens. Why?
