Using `plus' in 2.3.4

[Bohdan Liesnikov]

I would say that it's unfair to use + in attributes, as in
| D smallHundred {hundred.v = 5 + smallHundred.v}
or, otherwise, there is a chance to simplify whole translation by just adding translated values.
So, I would say, if one prefers to avoid arithmetic, then the only solution would be to explicitly define all the values.
