Thanks for the response. > It's both less bad and weirder than that. Integers are iterable.
Cripes! I've found the relevant mailing list thread you mentioned: https://groups.google.com/forum/#!msg/julia-users/bNDcBnF5hd0/q2GL2UtbmVIJ . Stefan mentions this decision could be revisited, so I'm hopeful this will eventually change. Julia isn't yet at a stage where backwards compatibility is critical, I presume?
