The problem with that is when you have code mixing ordinary plus and
overloaded plus.  To understand the code you have to decode it to
figure out which operator is intended. This is not something you can
do when skimming.

On the other hand overloading is  a rich metaphor than helps simplify
the syntax. For example, compare a complex library implemented with
overloaded operators to one with methods.

I think the way to resolve this is to take advantage of the fact we
are no longer limited to ASCII teletypes. There are glyphs and fonts
and colours that look similar to ordinary plus, but which are easy to
tell apart. Use your IDE/SCID to do the visual decoding for you.
