> Most humans are capable of using context to distinguish usage. Operator overloading in programming languages and in mathematics can be useful sometimes.

No doubt about it! But the difference as I see it, and what the OP is complaining about, is that in domain specific programming languages it's always possible to find a definition for the notation (an overloaded operator is defined somewhere, and so on); whereas in mathematics the only real definition is in the head of a mathematician.

I have to agree with the OP, that sucks. :(
