Steffen Schuldenzucker: Sure. GHC would prompt that. Jasper Van der Jeugt: Not working with ghc7. But there sure are some threads about this kind of things. I do not know if this is a bug of 6.* or 7, either.
Luke Palmer: Sorry, by special, I meant, for example, ["a", "b"] will be "ab" by default, but I want it to be "a,b". So I'd like to overload for certain types. Stephen Tetley: I think that are the only choices. The first is simple, but the second saves some code writing. After all, thanks.
