This would stop the warning of course, but it is actually valid Ruby code.

The warning is caused during creation of the documentation by the rdoc
parser. I think the parser has a bug, because :'foo' should be the same
as :foo, which returns the Symbol foo. You can use quotes to create
symbols with characters in it, that would otherwise cause the ruby
parser to misinterpret parts of the symbol as an operator, method call,
token delimiter, etc, in this case the '-'. Unfortunately the rdoc
parser doesn't seem to know about that.

I cc'd this mail to the ruby-core mailing list. Perhaps they can
implement a solution for this?

Kind regards,
Florian
