I tend to use a few tricks with map and grep to preserve the original array than to seek out and use something different. 
@new = map { ... } @{[ @original ]};

or even 
@new = grep { local $_ = $_; ... } @original;

If legibility (management overhead due to fussy boss) is a concern, I then choose to use an idomatic version of the for / do { ... } for loop. 
... for @new = @original;

[download]
or if you want multiple expressions within the loop.. 
do { ...; ... } for @new = @original;
