Possibly, for some personal concept of "good".

Why mad?

Others have also suggested this, and even wider overloading (including
variables). Arguments against the idea relied on subjective opinion, if
I remember correctly.

I do not see a pressing need to make constants (or variables)
overloadable. If I want to overload constants, I define overloaded
functions which return those constants. As for variables, they are
nearly always so local that overloading seems overkill.
