Aggregation is a very small JavaScript library for Node.js environments, providing just a single function, for use in ECMAScript 5/6 class inheritance based on mixins. It aggregates a base class and one or more mixin classes into an aggregate class, which then is usually subsequently used as the base class for another class.

Want to see what's inside a variable in a complete, colored and human-friendly way?

use Data::Printer; # or just "use DDP" for short

p @array; # no need to pass references

Code above might output something like this (with colors!):

[
[0] "a",
[1] "b",
[2] undef,
[3] "c",
]

You can also inspect objects:

my $obj = SomeClass->new;

p($obj);

Which might give you something like:

\ SomeClass {
Parents Moose::Object
Linear @ISA SomeClass, Moose::Object
public methods (3) : bar, foo, meta
private methods (0)
internals: {
_something => 42,
}
}
