Is there a way to fire add_action on a function that happens multiple times ?

usage, for example is adding a meta tag to wp_head each and every post that is displayed

The use of an anonymous function is bad code practice and I removed that part of the codex. Another reason it required PHP 5.3

The reason it fails it probably due an old PHP version.

Taken from the add_action codex http://codex.wordpress.org/**
Function_Reference/add_action#**Simple_Hook<http://codex.wordpress.org/Function_Reference/add_action#Simple_Hook>

add_action('wp_head', function() { echo 'something';})

is supposed to work, it just makes my site die
