No, but I do love Belgian fruit beers so I'm hardly a purist, my favourite is Cherry flavoured belgian beer, and it tastes fantastic, but then Belgian beer is sooooo damned good anyway. Cherry adds a refrshing tang and perfume to the beer which suits it. Peach flavour is nice too as is Raspberry.
Banana is a step too far in my opinion, too tropical and too dessert. Clove is used in mulled wine and I seem to remember having had mulled beer once, so I'm guessing clove has been used to flavour beer for a very long time indeed and just went out of fashion, and now it's being revived it seems alien and new.
