sortBy!(expr) is equivalent with sort!(expr_a < expr_b) so
there's no additional power to it. However, it does make some

didn't add sufficient value.
What do you mean by sufficient value?
Ruby has sort_by. I believe D would when possible should be a
superset of the union of powers available in other languages to
maximize the ease of porting code *to* D and the pleasure for
programmers to switch to D. I'll try to make this elegant and
useful and use it myself for a while. If it works for me I'll do
a PR still. Ok?
