error messages raised by python got me thinking.

I don't see how this could be possible. Addition always occurs on two
operands - so the best that could be specified would be the types of the
operands on either side of the operator.

Much the same information would be conveyed though if, in addition to the
line number, the column number were also displayed in the traceback.
