yeah, I added the check for namespaces to end on # or / because I (and many 
other people) often make typo's leading to strange behaviour. But 
technically it should be a warning and not an error message, since 
namespace prefixes can have arbitrary endings.

I'll change that for the next release, for now you can indeed not use this.  
Sorry.

thanks, that's a bug, I didn't think about it, but it will be hard to fix.  
The problem is that our meta-programming catches these invocations and 
tries to do something special with it, but this invocation is not a method 
in Ruby terms (methods cannot start with numbers) so the statement is 
treated quite differently than usual.

Yeah. You'll just have to create the resources using the most basic syntax: 
RDFS::Resource.new('urn:...:...'), i.e. using their full URI. The namespace 
syntax is only a shortcut but as you figured out, it won't work right now.
