* libguile/eval.h: * libguile/eval.c (scm_closure_apply): New function, applies a closure. Won't be necessary in the future, but for now here it is, with internal linkage. * libguile/gsubr.h: * libguile/gsubr.c (scm_i_gsubr_apply_array): New function, applies a gsubr to an array of values, potentially extending that array for optional arguments and rest arguments and such. * libguile/vm.c (apply_foreign): New function, applies a foreign function to arguments on the stack, in place. * libguile/vm-i-system.c (call): Add a case for procedures-with-setters (will go away when they are applicable structs). Instead of calling the evaluator for foreign functions, call apply_foreign.
