After having read
http://dlang.org/phobos/std_array.html#.replicate
I came to the conclusion that the lazy std.range:repeat is
preferred.
If lazy is good enough for you yes. AFAIK, replicate is *very*
close in terms of implementation to what a.repeat(n).array()
would do anyways. Heck, I'd be surprised if it did it
differently, since (again, AFAIK) repeat.array() is "optimal"
anyways.
I re-read the doc and implementation: replicate replicates a
*range*. It is a bit optimized to detect the case where the range
is a single element, but it still has to do the check, and even
then (implementation detail), it is less efficient. I might
create a pull to tweak that.
