Yes.  In the second case, the function returns a list, which is then
assigned to an array variable.  In the first case, you don't.  Usually the
impact would be minimal.  One really good reason to always use references
for passing around data structures is so that you don't make copies.  I
have a few large-scale applications with many megabytes of data that are
sped up considerably because of this ability to pass references.
