Re: A value for "nothing"

[HiPhish]

1) Huh, I didn't think this would work because the record type is already nil, 
but apparently it does. Good to know

2) `null` is bad because the predicate would be `null?`, which collides even 
worse with Scheme. Any other suggestions? `nothing`? `nul` with one ell? I 
think it would be too easy for people to miss that one letter and be confused 
why things don't work as they should. The MessagePack spec calls the type 
`nil`:
