in thread regexp wizardry needed

perlop says that /r is for non-destructive operation of a regular expression. You can simply replace that by introducing a temporary variable:

my $result = $example =~ s/foo/bar/r;

... can be replaced by

(my $result=$example) =~ s/foo/bar/;

In your case, you will have to make sure your map block actually returns the intended value:

... map { (my $result=$_) =~ s/foo/bar/; $result } @elements
