I'm experimenting with a patch for dictionary lookup caching, the main idea being avoiding the lookup of a constant (conames) in a dictionary if the dictionary didn't change since last lookup. . . . My opinion is that it would be by far better to do this ordering of conames at compile time
It would be nice if you could avoid introducing a new invariant that would be have to be maintained by other code generation tools or bytecode hacks.
