Address bug 1446847 without modifying the AST - simply explicitly set the slice step to None when a second colon is present but no step expression is provided. |

Logged In: YES user_id=699438 Does this generate the right bytecode if you're not using extended notation (a[:])? If so, it's better than my patch. |

Logged In: YES user_id=1038590 It does (confirmed by comparing dis.dis() output from my patched build against Python 2.4). This makes sense, since the generation of the implicit None step is inside the "sliceop" guard, so its only executed when the second colon is present. Checked in as rev 43121. |
