per-callframe constants segment layout:
constants segment starts with a list of fixed-width pointers. I/N entries are stored directly. S/P entries are pointers to later in the constants segment
The data segment has a couple options. It can be appended after the constants segment (either on the next page or immediately after), with the constants data being marked read-only. Alternately, it can just be another segment attached to a special register.
If callframes are analogous to subs, the constants and data segment can be analogous to lexical data.
If callframes are analogous to subs, how will recursion work?
* clone a callframe (when? before entering ( -> no state) or after entering (less waste, leftover state))
* need to work out calling conventions
