## NAME

MooX::Singleton - turn your Moo class into singleton

## VERSION

version 1.20

## SYNOPSIS

```
    package MyApp;
    use Moo;
    with 'MooX::Singleton';
    package main;
    my $instance = MyApp->instance(@optional_init_args);
    my $same = MyApp->instance;
```

## DESCRIPTION

Role::Tiny role that provides "instance" method turning your object into singleton.

## METHODS

### instance

```
    my $singleton = MyApp->instance(@args1);
    my $same = MyApp->instance;
    # @args2 are ignored
    my $above = MyApp->instance(@args2);

NOTE: Subsequent calls to `"instance"` will return the singleton instance ignoring any arguments. This is different from MooseX::Singleton which does not allow any arguments.
