   eq_(eval(let([(i,3)], 
                block(a, set(i, sub(i, 1)), 
                           if_(eq(i, 0), exit_block(a, 1)),
                           unwind_protect(continue_block(a), prin(2))), i)), 0)

Example #2

    if len(form) != 1: form = special.begin(*preparse(form))
    else: form = preparse(form[0])
    return special.unwind_protect(form, *preparse(cleanup))

Example #3
