Kinda nice...I think I'd be happy with little more than a bunch of
standardized named constants.

Unfortunately, most of the ones for Fortran only interpretively
keep track of units rather than enforce their use. That is, you
can't declare a variable to hold, say, only energy and have the
type system automatically detect an error if you ever try to
assign anything else to it.
The Ada method of this thread can declare such variables. That's
a considerable step forward. I think it may be possible to do it
with Fortran using parameterized types, though whether you can
do it with KIND parameters or only with non-KIND parameters
(or even, for sure, at all) I can't tell without an implementation
and some time to play with it.
