Thank you for the links, as well as the work on the SI units.
Browsing around, it looks like a lot of the library can be made Pure, with =
the exception of the irritating provision/prohibition of "statically compos=
ed compound constants" that appeared in the "Why can't objects be static in=
 Ada?" thread: https://groups.google.com/forum/#!msg/comp.lang.ada/8dMIIAOV=
7YQ/sscqy-tlCQAJ =E2=80=94 I think your SI-Units library is an extremely go=
od motivating example of *WHY* this needs to be changed, and will push for =
this change in the upcoming meeting of the ARG. (Indeed, changing this limi=
tation is orders of magnitude more useful than adding square-brackets.)

BTW
Are there any tips, in particular for using the library?
