compiled closures. Include "libguile/smob.h". (f_eval_closure): Removed. (scm_eval_closure_tag): New variable. (scm_eval_closure_lookup): Renamed from eval_closure. This function now takes a smob instead of a compiled closure. (scm_standard_eval_closure): Create a smob instead of a compiled closure. (scm_init_modules): Initialize the eval closure type as a smob. * modules.h (SCM_EVAL_CLOSURE_P): New macro. (scm_eval_closure_tag, scm_eval_closure_lookup): Declare. * symbols.c: Include "libguile/smob.h". (scm_sym2vcell): Call scm_eval_closure_lookup directly if THUNK is an eval closure.
