I should add that it is recommended to disable the monomorphism restriction, by putting

Hm, this is interesting. To me, most of the extensions are in the "crazy stuff only the profesionalls use" category - I successfully tip-toed around them so far. :-)
Are there other extensions which people would consider to be "generally good to have, unless you know a good reason *not* to enable them"?
I don't know of any others in that category. But there are a few others which are quite innocuous and if the compiler ever suggests you might like to turn them on, you should not hesitate, in particular FlexibleInstances and FlexibleContexts. -Brent
