I've also not used this before, but may now that I'm aware of it. Yes,
adding the infix declaration seems a preferable solution.
Something else to note and fix is that as it stands in the current darcs
version, wikipedia and wiktionary don't work properly with any of these
intelligent searches. (Probably because their urls contain the ':'
Haven't looked much at the code, but if it's not an obvious fix...
Rather than making the parsing even more complicated, hopefully there
will be alternate urls that will work. If I get a chance I'll check that
out later this week. Or it could just be noted in the docs and then yank
them from the `multi' foldr1.
