Hi all,
I was wondering if there is any interest in adding User-Defined Literals
(UDLs) to Boost.Units.
IMO, it could simplify some code and improve code readability in some cases.
For example instead of writing (it's a somehow artificial example)
    5.34 * si::milli * si::kilogram;
    1234 * si::kilogram;
one would write
    5.34_g;
    1234_kg;
Did you mean to write
5.34_g * si::milli;
or
5.34_mg;
?
No, to get grams you need si::milli * si::kilogram. I assume the intention is that the _g suffix already includes that scaling - otherwise it’d be broken.
