[go-nuts] database/sql and partial scan

Hello,
When scanning result of select query with joins, some rows may contain
duplicated data.
Here is a simple example to illustrate the problem:
http://play.golang.org/p/ca0MiPU_dO
To make partial scan (to scan only some columns), the example uses a dummy
variable (lines 49, 51, 65).
Could it be possible to make the Scan method accept "nil" value to say "I
don't want to retrieve this value" ?
Or do you have any other solution to avoid using "dummy" variables just to
make Scan method work ?

Thanks.
