3. Programming
I've noticed something interesting in C++ programming. I've always done tricky stuff with pointers and references to have functions deal with arrays. Doing exercises again out of a C++ book has shown me an easier way, I didn't even know was there. It's weird to me.
When dealing with arrays, it... (4 Replies)

autobox::List::Util(3pm) User Contributed Perl Documentation autobox::List::Util(3pm)
NAME
autobox::List::Util - bring the List::Util functions to autobox
VERSION
Version 20090629
SYNOPSIS
"autobox::List::Util" brings all of the functions from List::Util to arrays as methods.
use autobox::List::Util;
my @array = qw/ foo bar baz /;
print @array->first(sub { /ar/ }), "
"; # "bar"
print [5, 6, 3, 4]->max, "
"; # 6
print @array->maxstr, "
"; # baz
print [5, 6, 3, 4]->min, "
"; # 3
print @array->minstr, "
"; # foo
print [1 .. 10]->shuffle, "
"; #1 to 10 randomly shuffled
print [1 .. 10]->sum, "
"; # 55
print [1 .. 10]->reduce( sub { $a + $b } ), "
"; # 55
METHODS
first(coderef)
This method behaves nearly the same as the first function from List::Util, but it takes a coderef not a block because methods can't use
prototypes.
reduce(coderef)
This method behaves nearly the same as the reduce function from List::Util, but it takes a coderef not a block for the same reason. It
also has a bug (see BUGS)
shuffle
If called in scalar context it returns a reference to an array instead of a list. This allows shuffle to be chained with other calls.
max, maxstr, min, minstr, sum
These methods behave exactly the same as their List::Util counterparts.
AUTHOR
Chas. J. Owens IV, "<chas.owens at gmail.com>"
BUGS
The reduce method works with $main::a and $main::b, not your current package's $a and $b, so you need to say
print @array->reduce( sub { $main::a + $main::b } ), "
";
if you are not in the main package. Reduce uses $_, so it doesn't suffer from this problem.
