( #3333=superdoc: print w/replies, xml ) Need Help??

I think I'd like to see a looser coupling between find_above_average and calculate_average. And I would move the prints outside of the subroutines, to make them more generic.

use v5.14; use warnings; use IO::Interactive qw( is_interactive ); use Scalar::Util qw( looks_like_number ); use List::Util qw( sum ); say "Enter a list of numbers to find above average numbers, one per li +ne:" if is_interactive; my @numbers = get_input(); say "No numbers entered. Exiting" and exit if ! @numbers; my $average = average( @numbers ); say "The average is $average"; say "The above-average numbers are:"; say "\t$_" for above_average( $average, @numbers ); sub average { return sum( @_ ) / @_; } sub above_average { my $average = shift; return grep { $_ > $average } @_; } sub get_input { chomp ( my @numlist = <STDIN> ); return grep { length $_ && looks_like_number($_) } @numlist; }

Update: s/&&/and/ to fix a precedence issue.
