See the first two lines:

Intuitively I would have expected it to return 1001:1010 for the plus and 1000:1000:10000 for the multiplication, that is with the range collected before the operation and eventually reimplemented as range…

I am sure this is documented somewhere, just find it pretty odd…

`.+` and `.*` bind tighter than `:`, so the first two are equivalent to `(1000 .+ 1):10` and `(1000 .* 1):10` respectively. This behavior is certainly expected and unlikely to change.
