Hi hdb,
Yes, but why?
Checking sort documentation you will find this:

Warning: syntactical care is required when sorting the list returned from a function. If you want to sort the list returned by the function call "find_records(@key)", you can use:
@contact = sort { $a cmp $b } find_records @key; @contact = sort +find_records(@key); @contact = sort &find_records(@key); @contact = sort(find_records(@key));
Among other things..
That shows it can as well use: print Dumper( [ sort &uniq( @x, @y )  ] ); showing the list to be sorted is returned from a function.

If you tell me, I'll forget.
If you show me, I'll remember.
if you involve me, I'll understand.
