[Boost-users] [Q] using boost operators return types

I am working on a 
cmoney_t class using decNumber package (ICU license).
IBM has decNumber++ class but that one is for commercial use, so I
cannot use it.

I am using this example
http://www.boost.org/doc/libs/1_38_0/libs/utility/operators.htm#example

but cannot understand
why object is returned from those operators and not an object reference

second, I do not quite understand, what exactly is a set of 
'automatically generated' operators and would I figure that out.

I just want a minimum set of operators that implement typical operations
with money (I am using decQuad underlying implementation).

thanks in advance,
Vlad
