Well, I'd still be inclined to do something like:
@foo = @bar; for (@foo) { s/qux/waldo/ };
even if that isn't one statement as you probably meant.
But perhaps @bar is large enough and performance
requirements tight enough that you need to have @foo
only contain changed elements.
And you want it in one simple statement? I don't think
it can be done, depending on one's definition of simple.
Here's my best shot:
map { my $foo = $_; $foo =~ s/qux/waldo/ and $foo } @bar;
