I'm not sure about the theory of it, but if I load the module in GHCi and run head $ last $ initsR [0..100000::Int] I get a response *immediately*. If I run head $ last $ initsDL [0..100000::Int] I wrote this email while waiting for that to complete, and gave up on it. There may be an asymptotic performance bug here.
Sorry, I got the implementation of initsDL wrong (recursed into the wrong inits-function).
