=head1 NAME
SHARYANTO::Hash::Util - Hash utilities
=head1 VERSION
version 0.53
=head1 SYNOPSIS
use SHARYANTO::Hash::Util qw(rename_key);
my %h = (a=>1, b=>2);
rename_key(\%h, "a", "alpha"); # %h = (alpha=>1, b=>2)
=head1 FUNCTIONS
=head2 rename_key(\%hash, $old_key, $new_key)
Rename key. This is basically C<< $hash{$new_key} = delete $hash{$old_key} >>
with a couple of additional checks. It is a shortcut for:
die unless exists $hash{$old_key};
die if exists $hash{$new_key};
$hash{$new_key} = delete $hash{$old_key};
None are exported by default, but they are exportable.
