Can you elaborate a little on the value of using a dimensional analysis by
sharing some of these with us?

We are all assuming that there is a correctness payoff (some think a BIG
payoff) for using a system like yours/PQS/... but it is useful to have some
evidence that our instinct is correct. (This ignores the convenience of
handling units, of course).

The potential users of a 'units/quantity' feature are very much more
numerous than any uber-super-pointer IMO. In fact I would describe it as a
'killer application'. (I'd also like to throw in optional estimates of
uncertainty to further muddy the water).

So I am still very keen for the collective neurons of Boost (especially
those with Meta/Template minds) to solve it, if this is possible - I am
coming to fear that the language may not really make it as practicable as I


PS If only the MKS people had known the grief they would cause by making the
kilogram the fundamental mass unit... As a schoolboy, I thought it a little
odd, but its full horror never crossed my mind.
Some of the perpetrators must be still alive - I wonder if they are aware of
what they have done?
