D got it right. C++ returns an iterator which can be a bit
confusing. D returns a slice so it's meaning is much clearer.
No, according to docs D has defined the lower bound to be the
negation of the lower bound…

Quoting your link:
«5 is lower bound for the set { 5, 10, 34, 13934 }»
Hence if you lowerBound(4) the sequence
[ 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 ]
it should return
[ 4, 5, 6, 7, 8, 9 ]
not
[ 0, 1, 2, 3 ]
