Also a few more options (including a slice version):

As the input is never read until the array() is run, each
element in the array should only be copied from RAM to the
stack once.
And if you compile with LDC a lot of it can be inlined and the
stack copies of the range structs and elements should be
minimised even further.
Very inspiring snippets!
