Given i have defined the columns of interest in my data objects anyways...

  class User { name = null; email = null; }

... i wouldn't necessarily have to repeat them when writing my SQL:

   sql`SELECT ${Object.getOwnPropertyNames(new User).map(camelCase).join(', ')} FROM users`

Of course using a better helper function.

There's a few repetitive tasks when writing SQL where don't necessarily need a powerful query builder but still end up writing a few handler functions. Shipping some common helpers with the framework might be handy.
