Perhaps the docs are describing what the documenter hoped would be  
implemented. My C is very rusty, but I don’t see anything in string.c  
related to slice! that would raise errors for that.

I’d mention the bug on the ruby-core or ruby-doc lists (depending on  
whether the code or documentation is perceived to be at fault).

Neither do I.

Roger that. I’ll file a bug report.
