 =head2 What's wrong with using grep or map in a void context?
 
-Both grep and map build a return list, regardless of their context.
-This means you're making Perl go to the trouble of building up a

+The problem is that both grep and map build a return list,
+regardless of the context.  This means you're making Perl go

+intent is to iterate over the list then use a for loop for this
+purpose.
