Fatal error on plugin activation

Just found that this error happens because this plugin requires php 5.3+ (it uses an anonymous function).

I suggest to put this requirement in the plugin description.

I just got the same error and modified the code to pass a non-anonymous function. Now it works. Replace the add_action() code with the following and it should fix the error:

function add_snitch() {
	if (current_user_can('manage_options'))
	{
		new AcfFieldSnitch();
	}
}

add_action('init', 'add_snitch');
