remove support for "entities" -- a form of applicable struct
Entities were meant to be a form of applicable struct. Unfortunately,
the implementation is intertwingled with generics. Removing them, for
now, will make it possible to cleanly re-add applicable struct support.
* libguile/struct.h (SCM_STRUCTF_ENTITY): Remove.
(SCM_STRUCTF_GOOPS_HACK): New flag; sigh.
* libguile/struct.c (scm_make_struct): We make "entity" structs if the
GOOPS_HACK flag is set. This will be fixed when we rework flags and
remove hidden words.
* libguile/goops.c (scm_class_of): Structs are not applicable, for now
at least.
(scm_sys_inherit_magic_x, scm_basic_basic_make_class)
(scm_sys_allocate_instance, scm_sys_set_object_setter_x):
(make_struct_class): Adapt for no more entities (and thus no entity
flag).
(create_standard_classes): For some reason, generic functions were
getting the LIGHT flag set, after the ENTITY flag was removed; so for
now explicitly clear that flag.
* libguile/goops.h (SCM_GENERIC_SETTER, SCM_SET_GENERIC_SETTER): New
macros.
* libguile/objects.h:
* libguile/objects.c: Remove code for entities.
* libguile/debug.c: (scm_procedure_source): Only work with generics.
* libguile/eval.c (scm_trampoline_0, scm_trampoline_1)
(scm_trampoline_2): Only handle generics.
* libguile/eval.i.c (CEVAL): #ifdef out the pieces about entities.
* libguile/procprop.c (scm_i_procedure_arity): Remove support for
entities.
* libguile/procs.c (scm_procedure_p, scm_procedure, scm_setter): Remove
entity support.
