> projects that bring him joy and/or money I believe author pursued projects that build him joy (creating a web framework in Haskell) vs. what would bring him money (iOS apps). The two are not the same. Money can easily cloud the picture. For some people re-inventing the wheel in Haskell may be what brings them joy. There's also nothing wrong with re-inventing the wheel: I am very glad my sports car has forged 19" alloy wheels rather than slices of a log. Reflection is great (it's what made even static language frameworks like those in Java and C# successful), but it's also a poor substitute for genuine meta-programming as afforded by languages in the Haskell and ML family.
