See, that's one of the examples I had in mind, because the way 
I'd get the length of a static array in real code is

     arr.length

I assumed you knew about that and were just using the example to 
demonstrate template argument deduction. :)

I'm not familiar with Julia's value types, and reading the linked 
page doesn't give me a clear idea what they are used for. Again, 
the example does a decent job showing how template value 
parameters [1] work, but it doesn't give me much of a clue about 
why I'd want to use them. Perhaps that's just me, though, and a 
programmer with a background in Julia would understand better.
