-- This is a very simple example of parsing and generating json with Aeson,
-- by a haskell newbie and intended for newbies.  
--
-- This almost certainly contains a number of bad practices.  It works for 
-- me and hopefully will get you started.
--
-- I couldn't find a stand-alone example of Aeson usage and found it tricky to 
-- get going.  For example, if you don't realize to enable the language extension

• Red area is a result of the upfront, fixed cost of learning Haskell vs Java.
  • The company pays this for each new hire.
• Yellow area is the developer's productivity gain once they're "over the hump."
  • The company can benefit from this, but it must first reach a break-even point vs the cost of learning.
  • If average employee tenure is less than this break-even point, the company is taking an absolute loss on each employee.
  • For Haskell to truly be worth it from a business perspective, the average tenure must not just eclipse the break-even point, but it must go further to account for the opportunity cost of better productivity during that learning period.
• However, employees always benefit from this regardless of turnover - they get to take the productivity gain with them. This - in my opinion - naturally results in some tension.
