have a look at codeconscious (Brett),

he says
Because I've had too many years of SQL buzzing around my head I thought I would
create a few cute functions like array-project, array-select and array-join. The
functions work on data that is assumed to have the structure returned by the array

seems to be a bit of sql with rebol-blocks as tables.
other approach, but one could write block-to-objects and vice versa?
if you think its worth something we could help?
