Indeed, my experience with Julia is zero and I don't know what 
@btime is actually testing. Just copied it from howto benchmark 
Julia code page. I would honestly test the time it takes the 
actual script to run like "$ time julia demo.jl" because it does 
take some time before it precompiles the code so you don't feel 
those reported 0.1 seconds at all. And if you do data processing 
and scripting, console responsiveness and processing speed is all 
that matters to me at least.
