[Haskell-cafe] Investing in languages

There's no doubt that languages like Haskell go through extra efforts to
make it *harder* to write incorrect code, and along the way they also
make it harder to write code at all.

So maybe it will take your guy a week to get the code written in
Haskell, whereas a couple days were sufficient in Java.  But that's
without counting the subsequent month during which the Java code will
have to be debugged before it actually works ;-)

IIRC it was Bob Harper who said a good programming language should be
hard to write (but easy to read, of course)?
