title='use malloc() for better performance of some list operations'updated_at=<Date2018-08-11.13:14:26.194>user='https://github.com/sir-sigurd'
Currently list concatenation, slicing and repeating operations are using PyList_New() which allocates memory for the items by calloc(). malloc() could be used instead, since the allocated memory is overwritten by mentioned operations.
