Well then an alternative is to use brackets. 
 
map { something } uniq(@arr1), uniq (@arr2).

The saving of 4 brackets 
map { something } uniq @arr1, uniq @arr2.

comes at the cost of looking in the code and finding out (and remembering) the signature. If the whole developing team uses List::MoreUtils and prototypes are well understood by everyone then its ok to save the brackets. Otherwise, and that is my personal opinion, preserve the default semantic of list flattening and be explicit by using brackets.
print+qq(\L@{[ref\&@]}@{['@'x7^'!#2/"!4']});
