in reply to Re^5: Automatically add all defined functions to your @EXPORT
in thread Automatically add all defined functions to your @EXPORT

I agree that 
@var = something1 grep {
         something2 &&
         something3
       } map {
         something4
       } keys %something5;

isn't all that readable, but you can do 
@var = something1
       grep {  something2
            && something3 }
       map  { something4 }
       keys %something5;
