in reply to Re^6: the '..' operator and decreasing values
in thread the '..' operator and decreasing values

There's no bug. As of 5.8.6 (or maybe 5.8.5, didn't check that) the reverse is indeed optimized away. However, the .. operator is still evaluated to produce the full list (at compile time). So there's a potential for optimizing that away also, but you can't actually call it a bug.
