So we think the printer, disk, or plotter is going to push the bottleneck onto the code
behind this choice? :)
You know, by being really really fast printers, disks, or plotters?
If this was Java, I would agree with you, since you cannot instantiate anything without
"new"ing it. And once you've paid for that heap operation, then by all means it is faster
to reuse that object with a reference.
But this not Java, and we are not talking about a heap operation, simply an on stack
construction. And you have such nice looking similar functions which return the converted
But again, do what you want. I won't mention it again.
