[Python-ideas] Implementing a set of operation (+, /, - *) on dict consistent with linearAlgebrae

Personally, I would be able to use the module you are proposing to
accumulate arbitrarily-named measures. I can not think of a use case for
division, but it would be nice for completion. I have made my own
library that implements a small part of what you propose .
I was looking through the pstats.py  source code; and I thought it
could benefit from vector operations. I have seen other code that
collect measures have the same redundant pattern. Maybe some fancy
regex can identify other += code sequences that would benefit. If you
make a module, and show how it can simplify pstats.py, maybe you have a
 "vector" addition? -
