That was pretty much my position, too -- I was looking for something more
semantically appropriate. My task was trivial to solve in one or two ways, I
just didn't see any examples on how to do this stuff elegantly. What I am
really looking for is something expressive like
$product->find_prices(query => [ region => 'UK' ])->delete_all;

What always annoyed me about this technique is that it looks like
you're losing all the prices. Setting something to undef generally
has that meaning in Perl. I would rather write
$p->forget_prices();
or something like it (the same effect could be achieved behind the
scenes). This should definitely not be a helper function, if it's
used, because the whole point is that the default semantics should not
be confusing to new users. Perhaps I'm the only one of this opinion.
