Whenever you declare something in a nested context, it may or may 
not have a hidden context pointer, depending on the type, and the 
implementation.

"static", in this context, ensures this does not happen. It's not 
actually *needed* in this context though. It's more of a matter 
of style.

In your example, the function was declared in global context, so 
the "static" would have been gratuitous.
