Some specialization statistics: https://gist.github.com/sweeneyde/49cc3a9d074d56cf095cb0a42d13d7a4 Including 3 opcodes: COMPARE_OP_INT and COMPARE_OP_FLOAT and COMPARE_OP_STR (equality only) seems to give pretty good specialization numbers, better than just 2. |

Is COMPARE_OP worth specializing by itself? Most comparisons are followed by a jump, and much of the overhead is in the branching around the choice of operator as well as pushing and popping (with inc/decrefs) a value that has only one bit of information (True/False). |
