Detailed Description

namespace unitsymbol.

provide a namespace with abbreviations for some of the above units, i.e. lots of small symbols. Can be very handy but very dangerous as well.

a) This namespace is somewhat useless if you use fully qualified identifyers: unitsymbols::m is not more handy than unit::meter

b) This namespace is somewhat dangerous if you just import it by using namespace unitsymbols, since the probability of name crashes is quite high.

c) Best practice is probably just to pick those names that you really need: using unitsymbols::h; using unitsymbols::min; time duration = 2*h + 30*min; (But then, we could as well define a const static copy locally, or provide a local reference to the already existant global const static quantity)

Use with care. Caveat emptor.
