Or dictionary/set comprehension? You could probably override it using Python’s extension system. Forgive me, I know Python very well, but not C/C++. I’ve learned to make no assumptions.

Check out the Python bytecode in the article, and remember that bytecode is only generated once from the text of the program (but executed many times). "{}" is translated into a simple "make a dict" instruction.
