This is an important observation.  My vision for the GSoC project 
was targeted primarily at druntime. D memcpy would rarely, if 
ever, be invoked directly by most users.  Expressions like `dst[] 
= src[]` and other assignment expressions that require memcpy as 
part of their behaviro, would be lowered by the compiler to the 
runtime memcpy template.
