*Even* with t1_quantity (fixed units) you would get some 'free' units output ;-)
[cut user settable units]

Yes. t2_quantity should be useful for that. Typically you can make a units
map<unit_string, quantity_w_unit>.
t1_quantity is useful to describe the quantity_w_unit, t2_quantity to hold
runtime unit and convert to t1_quantity
I had an example, but in a previous version of PQS. Not tried to make a GUI
widget of it yet though ;-)

Yep ... todo!
