I think
pushis more appropriate thanconcatfor collecting variadic into array with repeated calls. I usedconcatoriginally as "safer" to avoid mutating previous value, but in normal usage the routine has created the array itself with the first value so ok to mutate.Added a couple of missing tests that a default array does not get appended to.
