It does have slight perl 6 vibes. Scheme was a very small language with high expressive power (compiler under application control and first class continuations). It picked up cleanups and fixes until revision 4 or 5ish, the r6 changed direction and went for relatively big language. More like common lisp. R6 fractured the community, some people stayed on R5 indefinitely. R7 tried to handle this with a small and large revision, shipped the small part a decade ago, and the large one is a work in progress (and seems at risk of getting the same reception r6 did). So whether it is scheme, or whether it's an obscure project using the same name, kind of depends on perspective.
