Well in the true OO world the ability to "overload" a message (aka what
is sometimes effectively an operator) allows a wise designer to apply
the traditional meaning of that message (operator) to a new kind of
object.  Attempts to change the meaning of a message (operator) when
applied to already well known objects is forbidden by good taste and
sane reviewers.

C++ being a bit of a dog's breakfast seems to have given some people the
idea that they can get away with abusing operator overloading for what
can only amount to obfuscation.
