Yes, that's the only thing I've ever seen it used for. I don't think it's worth 
the cost. Translation only needs to be done once. 

Sure, the cost is small and to do anything fast with Guile arrays it's 
necessary to go down to C/C++ anyway. The wrapper checks the bounds and I can 
forget about it.

I just don't think of arrays as a complex data structure where it's ok to pile 
features at the foundations.
