No Namespace for Macros

Erlang does have the concept of namespace for the functions( we do
Why does it not have this concept for macros?
Consider this scenario: I have an application which deals with the value of
some things. (lets say a house & a car)
So, I define macros in two different files for the things.
Now, My application file could be something like this
-include("valueCar.hrl"). %% This will not compile... ll give 'redefining
macro error'... assume it is allowed in erlang
case X of house -> ?valueHouse:Value;
car -> ?valueCar:Value
This is just a cooked up example. One may have this kind of need in a big
For exapmle, Java supports this (public static final variables).
