what about the idea that the interpreter preallocates and preinitializes the tuples and dicts for function calls where possible when loading a module?

This would not be thread-safe. Locking would be needed around uses
of the preallocated objects, and that might take away some or all
of the gain. It would also introduce unexpected interactions
between threads.


Thread safety is not a problem (because of GIL). The problems are the reentrancy, functions which save references to args and kwargs, and the garbage collector.
