[julia-users] Re: What's new in 0.3?
Thanks again for the pointer to the release notes. The issue I raised was not dealt with in the release notes: namely, 1:5 == [1:5] evaluates as true in Julia 0.2 but as false in Julia 0.3. I think the new behavior is a problem. I was happy with the old behavior, but if this is a bad idea for some reason, I would prefer that Julia raised an error in this situation rather than give a result that (in my opinion) is wrong. Certainly Julia compares objects of different type for equality (e.g. 0==0.0) so the fact that 1:5 and [1:5] are different types is not the issue.

The NEWS.md file does cover this: • Ranges and arrays with the same elements are now unequal. This allows hashing and comparing ranges to be faster.

My bad. Didn't read this carefully enough to realize this comment applied to my issue.
