The usage wasn't immediately apparent to me.
It suprised me that I had to look a the docs to use this one.
Take for example:
float myfloats[24] = {0};
size_t count = sizeof boost::count_of( myfloats ); // count = 24
This seems to suggest you are getting the size of the count of the array.
If spoken aloud that brings to my mind something like:
sizeof( size_t ) == sizeof boost::count_of( myfloats )
I would have expected
float myfloats[24] = {0};
size_t count = boost::count_of( myfloats ); // count = 24
The sizeof seems like an implementation detail.
Is it possible to hide it from the user?
