JM> one of the most common operators.

especially in comments ;)  add the following filter to strip them:

import System.Environment

main = interact (noStream.(unlines.map noEnd.lines))

noStream ('{':'-':xs) = noInStream xs
noStream (c:xs)       = c:noStream xs
noStream ""           = ""

noInStream ('-':'}':xs) = noStream xs
noInStream (_:xs)       = noInStream xs
noInStream ""           = ""

noEnd ('-':'-':xs) = ""
noEnd (c:xs)       = c:noEnd xs
noEnd ""           = ""
