Which is still signed.
This is disappointing. I'll only get half of the indexable space... can I get something in return? Having a negative index mechanism, like in Python, would be a way to alleviate some of the pain. Otherwise can you explain the rationale for not using signed? _______________________________________________ Interest mailing list Interest@qt-project.org https://lists.qt-project.org/listinfo/interest
