Rather strange meaning attached to "C-implemented". The implementation generates the code that would have been generated had you written out the loop yourself, with a speed boost (compared with the fastest DIY approach) from using a special-purpose opcode LIST_APPEND. See below.
Fair enough. ;)
So you basically replace the SETUP_LOOP, CALL_FUNCTION, POP_TOP and POP_BLOCK with a DUP_TOP and a LIST_APPEND.
