It would be a substantial change to the behaviour, and to do it
properly we'd have to change to_date() to actually parse separator
characters as well.
That is, you can currently write to_date('2009/09/19', 'YYYY-MM-DD')
-- it doesn't matter what the separator characters actually look like,
since per the format pattern they cannot affect the date outcome.
This naturally leads to the question we always have to ask with these
functions: What Does Oracle Do?
But FWIW, a -1 from me for changing this.
Cheers,
BJ
