Review comment:
I thought about that but could not really think of a good name, that is
why I left it.
The difference is in the description of the function: type is not defined
becomes 0, type is not defined becomes max Quantity (i.e. max int64)
Since Quantity can never be larger and thus will always fit, the value check
is skipped:
```
if skipUndef && !ok {
continue
}
```
implements the difference between the two.
