On reflection, that's a good idea.  I'll change it.

I'm going to extend the (srfi x4) library so that it reexports SRFI 4, which will be basically just this with the addition of list->@vector, @vector->list, and @vector.  @? would be a good addition.

Ah, I took (srfi x4) for an implementation detail - is it then an official library?
I think the libraries defined in a SRFI should all fit within that SRFIs namespace, hence the suggestion (srfi 160 base).
