Python 3.14, set to release later this year, will introduce a new type of interpreter that can enhance performance by up to 30% without necessitating any changes to existing code. This improvement is based on an optimization method referred to as "tail calls," which speeds up bytecode instruction dispatch via a C compiler, though it does not imply any direct support for tail call optimization in Python itself. Existing Python code and C extension modules will not require recompilation, and the new interpreter adds
