Do you think that's really necessary? One of the main goals of Julia is
to make it possible to write efficient code without mixing a high-level
and a low-level language. Carefully written Julia code should be quite
close to C in terms of performance.

I think you should have a look at this thread:
https://groups.google.com/d/msg/julia-users/VeaoUzvEwZQ/1Pa_IClBvYIJ
(This could probably go into the manual at some point.)
