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.
