#+title: representation of Scheme types
the Scheme unitype is encoded as ~(ref eq)~ with immediates in ~(ref i31)~ and heap objects in ~$heap-object~:
#+begin_src wat
(type $heap-object (sub (struct (field $hash (mut i32)))))
#+end_src
* immediates
all immediates are stored in ~(ref i31)~ and thus must fit in 31 bits. the most important immediate, the integer, is indicated by a null low bit.
#+begin_example
XXXX XXXX XXXX XXXX XXXX XXXX XXXX XX00
||
|\ used by wasm's i31 rep
zero indicates a 30-bit fixnum /
in the upper bits
