No realistic discussion of such a proposal can be undertaken
with reference to/ comparison with boost.spirit which has been
in usage for 10 years and has been continually updated, enhanced
and maintained over that period. You should start out by taking
a careful look at spirit and contrast your proposal with this
mature library used for the same purpose.
