  It's an array. Fixed arrays have a numeric value inside the 
brackets, the LU is because it's a 64bit compiler/machine (size_t 
being long), otherwise it would say [7u]. I have similar problems 
sometimes, if the sizes match perfectly you won't have problems 
(and will copy), if they don't you can make a slice out of it and 
pass it.

  I'm not sure if it's specifically documented, more like how it's 
seem to the compiler (for type checking).
