I, a pilgrim, seek deeper insight to things Perl.
There are certain operations on arrays for which most programming languages have functions, but for which Perl does not. There are instructions on how to do these things in the perldoc, but they aren't core functions:
- Getting the maximum or minumum element in an array of numbers;
- Getting the union, intersection or difference of two arrays.
I expect that this is not an oversight, but is rather part of the Perl philosophy. But I cannot divine why. Will a brother monk instruct me?
