Because it's a lie. "delete" should delete something, and not be
overloaded to perform non-obvious, unrelated logic. A perfect example
is how the proposed usage of "delete" confused Frank Mori Hess. Was it
unreasonable for him to see "delete" and assume that it was actually
deleting something?

The same can be accomplished using type traits or function overloading.
