Hi there,

Say, if I have a set A{0, 1} and now I insert B{0.2, 0.8} into A, using
that function, I'd expect A{0, 0.2, 0.8, 1}, but what I really get is A{0,
1};
If A is {0, 0.1}, I'll get A{0, 0.1, 0.2, 0.8} as expected...
So it looks like that insert(ordered_unique_range_t...) can only insert
elements subsequent to A.

If this is the expected behavior, this function is useless to me, or is it
a bug?

File attached.

Thanks.
