See #4167 and #4127 for the merged PRs.

Also need a note on iota.length being fixed to size_t, regardless of the type being iterated.

Edit: A possible update (left out macro stuff):

iota.length is now fixed to size_t instead of the type being iterated

...

iota.length is now returned as size_t. This means if you are on a 32-bit CPU and you are using iota to iterate 64-bit types, the length will be truncated to size_t. In non-release mode, you will get an exception if the length exceeds size_t.max in your call to iota.

Added - thanks for reminding ;-)
