Yeah, that's caused by Ruby parsing ":foo" "-" "bar". Sorry, I should
have used the proper syntax, Jacob is right of course, you need
:"foo-bar" or :'foo-bar'.  So the list of options now looks like this

object.send "foo-bar"
object.send :"foo-bar"
object["foo-bar"]
object[:"foo-bar"]

Plus same methods with double quotes replaced by single quotes.
