NOTE: I don't know R, so I may be talking rubbish...
I *think* the idea of whoever suggested it was not that the *user*
should have to do things like the above, but that the INTERFACE
between R and SQLite should do it. In my simplistic view the interface
"knows" the input is a date ("as.Date(..)") and so would tack the
"...__date" hint on to the column name when talking to SQLite. Coming
back out of SQLite, the interface would recognize the "...__date" and
turn the value into an R date.
