Note: There are another shared key.
* 128 bytes for ~3 items
* 224 bytes for 4~5 items
So, let S = how many instances shares the key,
* 90 + (96 / S) bytes for
Hi all,
I think we need some more data before going any further reimplementing
dicts.
What I would like to know is, across a set of Python programs (ideally a
representative set), what the proportion of dicts in memory at any one
time are:
a) instance dicts
b) other namespace dicts (classe
As my last email, compact ordered dict can't preserve
insertion order of key sharing dict (PEP 412).
I'm thinking about deprecating key shared dict for now.
Instead, my new idea is introducing more compact dict
specialized for namespace.
If BDFL (or BDFL delegate) likes this idea, I'll take anot

The documentation states: """Objects such as modules and instances have
an updateable __dict__ attribute; however, other objects may have write
restrictions on their __dict__ attributes (for example, classes use a

FYI, Here is calculated size of each dict by len(d).
