and whatever hook_load() is should be made.  

I don't have a great answer on this myself.  Functor strikes me as the 
correct term but as an inappropriately challenging word.  A functor to 
me represents an object that is a calling proxy for an actual 
implemented function.  One can have multiple functors, but only one 
implementation.  'callback' as the prefix term is also slightly off.  
I'm not passing the function pointer into something to get called back on.

What about slight variations on either of these.  func_load() or 
callout_load(). 

'func' as the prefix implies more of a function rather than an object 
representing a function.  I'm tainted by a C++ background and may be in 
the minority in how I read 'functor' vs. 'func'.

'callout' is fairly descriptive of what is happening.  Something in core 
is calling out to my function.  As I've left this message sitting to 
think about it more I find that this term sits best with me.  Am I 
allowed to +1 my own idea?  :)

I like the current, nice, orthogonal system.
