avoiding loops, allocation using arrays and ranges

.array allocates a new array. I want to store the result of v in a
buffer that I have preallocated
in my case this just happens to be a[];

This is quite important.
This is also the step I would like a more elegant way to deal with.

Thank you I will certainly take a look at these.
