copy lists that are known to be finite (though not necessarily proper). * debug.c (scm_procedure_source): Don't have scm_unmemocopy treat a closure's argument list like an expression of a body. * eval.c (unmemoize_expression, unmemoize_exprs, unmemoize_and, unmemoize_begin, unmemoize_case, unmemoize_cond, unmemoize_delay, unmemoize_do, unmemoize_if, unmemoize_lambda, unmemoize_let, unmemoize_letrec, unmemoize_letstar, unmemoize_or, unmemoize_set_x, unmemoize_apply, unmemoize_atcall_cc, unmemoize_at_call_with_values, unmemoize_future, sym_atslot_ref, unmemoize_atslot_ref, sym_atslot_set_x, unmemoize_atslot_set_x, unmemoize_builtin_macro): New static functions and symbols. (scm_unmemocopy): Rewritten in terms of the above. scm_unmemocopy now has a slightly different meaning: The memoized form that is receives as its argument is now interpreted as a sequence of expressions from a body. (unmemocar, scm_unmemocar): Since the whole functionality of unmemocar and scm_unmemocar is not needed any more, scm_unmemocar has its old content back and is deprecated, while unmemocar has been removed. (SCM_BIT7): Removed. (CEVAL): For unmemoizing a single expression, call unmemoize_expression instead of scm_unmemocopy, which now expects a sequence of body expressions. Eliminated unnecessary empty environment frame when executing let* forms. Eliminated unmemoization step from evaluator.
