Actually no, not particularly. BLR survives only as far
as par.c in jrd. What's being proposed is moving DSQL
one step further into the engine so it produces the same
sort of output as par (parse) or the first phase of cmp
(compile).

That's an approach. But I think the current code has enough strength
that we can replace bits in place, rather than wholesale.
