Computations with units (meters, seconds, ...)

I would hope instead that anything which becomes part of the language will be more fundamental and the notional syntax can be illustrated as

real, physical_quantity(dimension="LMT-2") :: some_force ! or some such representation of dimension of quantities

and later when conversions can be introduced, it may include

real, physical_quantity(dimension="LMT-2",unit="N") :: some_force
