I don't understand how that's relevant to the point.
I'm confused. Do you know that he wrote ledger in C++?
Sorry, I thought you were making a point I did not get citing him in comparison with a haskell project. Apologies, I misunderstood.
No worries, I probably wasn't very clear. I wish that someone like John Wiegley would give us his thoughts on Haskell/Lisp/C++. I have a lot of respect for him; he's made big contributions to Emacs and wrote a Common Lisp version of ledger in addition to his C++ version.
I'm confused. Do you know he is a prolific Haskeller and maintains many libs?
