# NAME
Data::NestedParams - entry\[title\]=foo&tags\[\]=art&tags\[\]=modern
# SYNOPSIS
use Data::NestedParams;
my $expanded = expand_nested_params(
[
'entry[title]' => 'foo',
'tags[]' => 'art',
'tags[]' => 'modern',
]
);
# $expanded = { entry => {title => 'foo'}, tags => ['art', 'modern'] };
# DESCRIPTION
Ruby on Rails has a nice feature to create nested parameters that help with the organization of data in a form - parameters can be an arbitrarily deep nested structure.
The way this structure is denoted is that when you construct a form the field names have a special syntax which is parsed.
