For such kind of code I suggest to use UFCS chains.
Can you explain in a little more detail? It's not an aspect
of programming I'm familiar with.
auto r1 = iota(_sumHead[v], _sumHead[v + 1]).map!(a =>
_tail[_indexHead[a]]);
auto r2 = iota(_sumTail[v], _sumTail[v + 1]).map!(a =>
_head[_indexTail[a]]);
return chain(r1, r2);
Ahh, OK. To be sure I understand what you're getting at, is it
just that it's more elegant to write it this way (I agree:-), or
is there a performance benefit in the iota().map!() form (or to
separately generating the ranges and then chaining them)?
