| 4 | This is not going to be fixed. It is generally agreed that there is no |
| 5 | point in writing a bytecode verifier and putting it in CPython just for |
| 6 | this. Moreover, a verifier is bound to accept only a subset of all safe |
| 7 | bytecodes, so it could lead to unnecessary breakage. |
| 8 | |
| 9 | For security purposes, "restricted" interpreters are not going to let |
| 10 | the user build or load random bytecodes anyway. Otherwise, this is a |
| 11 | "won't fix" case. |
