This is a silent bug because we are calling the 'fixed_point' function with 'thresh' set to 0:
bound_free_vars = fixed_point(start=set(), step=get_bound_free_vars, distance=get_size_difference, thresh=0)
However, it's important to note that the 'fixed_point' function was not designed to handle 'thresh' values below 0
