Sadly, I suspect it will be a long time before this is usable by folk in
the field :-(

It's a pity there is not better support for arbitrary size integers and
floating point in D. Hardware integers are too limited and hardware
floating point far too inaccurate for an awful lot of computing out
there (*). Groovy is getting a lot of traction exactly because the
default floating point is BigDecimal and not IEEE754.


(*) I know games requires speed above all else, as does a lot of the
sort of calculations I have done in the past, but these calculations
generally need very few significant digits of accuracy. We won't mention
the calculation that are just wrong because insufficient attention to
error management occurs.
