With D you can forward to best suiting implementation. What libc 
does it performs various runtime checks in order to figure out 
what is the best way of copying provided input. With D it should 
be possible to make certain checks at compile time. Secondly C's 
memcopy is a big function not because its best for performance 
but because of convenience. With D we can have many smaller 
functions and they would be selected by template magic.
