None of these should compile. But they do, and we only get told at runtime that someone goofed.

I get that the base `Page` object takes generic `var Record: Table` arguments, so at the base level those can't be validated - but it is hopefully possible for specific Pages, which have a specific SourceTable set, to error out if they are passed a Table that is not of the same type.

Please can you consider doing this? It would catch common thinkos and save much time.

I might've missed some methods taking `Record: Table` arguments from my example, in which case, please include all such methods in this fix.
