> With the addition of scalar functions, we should have a basic set of built-in functions.
> This issue represents the need to have basic type-conversion functions for converting
values into a new data type. I propose to add 4 built-in functions for that:
> TO_STRING
> TO_NUMBER
> TO_DATE
> TO_BOOLEAN
> When possible this conversion should obviously be done by the backing database. But initially
we should also cover all data context implementations by having a client-side application
of it.
