Hi all.
While reading guile sources I happened across the implementation
of struct scm_print_state. ref: libguile/print.h
It (tries to) map a C struct to a set of Guile struct fields:
ref: SCM_PRINT_STATE_LAYOUT.
I *could* be missing something, but I think my angst can be represented

One of the benefits of using a mutating stack for the variable bindings are

would benifit guile-log logic programs and the kanren and prolog
interfaces. The current options are to use a light version that take care
