Thus speaketh the report (http://haskell.org/onlinereport/lexemes.html):

symbol   ->      ascSymbol | uniSymbol<special | _ | : | " | '>
ascSymbol       ->      ! | # | $ | % | & | * | + | . | / | < | = | > | ? | @
        |       \ | ^ | | | - | ~ 
uniSymbol        ->      any Unicode symbol or punctuation

Punctuation characters are legitimate for operators.
