Yes, I use them too, and they really do a good job. But I'm bothering 
about the performance because first you can't be sure that they are 
inlined, second you have to implement them and for example if you use a 
struct you didn't create that doesn't have this, what can you do.
Also I wonder what is behind this opCall, how far they're optimized and 
inlined. I suppose that they create additional operations
