* libguile/programs.c (try_parse_arity): New helper, to parse bytecode to determine the minimum arity of a function in a cheaper way than grovelling through the debug info. Should speed up all thunk? checks and similar. (scm_i_program_arity): Simplify. * libguile/gsubr.h: * libguile/gsubr.c (scm_i_primitive_arity): * libguile/foreign.h: * libguile/foreign.c (scm_i_foreign_arity):
