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'm still a bit confused about the fact that -vgc gives no
warnings about GC-allocations, though.
Strange indeed. Both solutions allocate a slice, and then append
that slice. The "s[]='*'" Solution I gave you will not create a
temporary allocation.
