Comment (by nacin):

 Replying to [comment:10 joehoyle]:
 > So  many plugins do the above with `add_action( 'init', 'my_plugin_init'
 );` that doesn't make sense to be a function. It's not reusable, it's not
 meant to be added / remove by third parties, so probably shouldn't be
 added as a top level function. Without closures you end up loads of once-
 use weirdly named internal functions for callbacks, making it much more
 difficult to have the codebase coherent.

 So, I certainly see where this sentiment is coming from, and am inclined
 to agree. But I'm not sure it scales well beyond a single hook. Once you
 need to attach the same callback/closure to multiple hooks, I think that's
 generally a really good indicator that we've crossed (or at least
 approached) the point of reusability.
