Re: unboxed structure fields (or class slots)

There are several easier ways than using the FLI, all of which come down to using a double-float array to hold the values.

The reason I'm asking is because I've been thinking about generalising my struct-of-arrays tool (whose purpose is to avoid this problem for implementations where it happens, amongst others).  I'm assuming LW can't do this.
