Thanks for the detailed response c:

The blocker is that AFAIK we can't tell if a record-field was defined as
thunk-ed or delay-ed outside of the expansion of the `define-record-type*'
form that defines it, nor programatically access it's getter/setter (the pair
`(guix records)` defines, which accounts for eg. thunk-ing, and is distinct 
from the
underlying pair returned by eg. `record-accessor').
