From the GHC wiki:
It's much better to write code that is transparent than to write code that is short.

Often it's better to write out the code longhand than to reuse a generic abstraction (not always, of course). Sometimes it's better to duplicate some similar code than to try to construct an elaborate generalisation with only two instances. Remember: other people have to be able to quickly understand what you've done, and overuse of abstractions just serves to obscure the really tricky stuff.

I'd dispute the "often". Also, the fact that such situations may exist is no excuse for not providing some abstraction mechanism in a language! :-)

I think this is more a commentary on the stupidity of people rather than languages. Languages often provide way too much abstraction given their target audience.

(misspelled 'too', I'm stupid)
