    I would say that this is a strike against allowing parameters to be used
    in constant functions. The assumption that it was sufficient to restrict
    them to parameters defined before the use of the constant function is
    based on the invalid idea that parameter values are determined in a single
    linear pass through the module from top to bottom. They shouldn't have
    been allowed to use parameters in their definitions at all.
