util.OrderedProperties, util.OrderedDict etc. rewriting with C

[Former user]

I see you use it frequenly as base types like dict and list.

Probably rewiriting this simle classes using plain C will increase summary performance. If you accordant to me I can rewrite it's myself or charge it to my team.

You can propose another objects to rewrite. Or, please, describe me reason for unimportant effort of this optimization.

i never want any compilation of C code to be part of a core SQLAlchemy installation; by default its pure python.

If you would like to provide an extension which replaces the OrderedDict/OrderedProperties classes inside the util module with native objects when installed, i may consider having that in a new contrib/ folder.

however, one thing to be careful about optimization is that it is needed and is the appropriate optimization for a particular operation that has been observed to be too slow. Have you identified OrderedProperties and/or OrderedDict as a significant factor in the performance of some function ? do you have a test case I can run with the profiler module ?

this ones falling off the statute of limitations....if you have further ideas on having C-versions of things, please reopen...
