[Gambas-user] Why is val() so roundabout?

[Eilert]

This is a good idea, although it takes yet another function to 
implement. Checking with IsNull() is a way I didn't see.

But why did Benoit implement val() this way? I don't see any sense in 
it, but there might be one (I'm not a professional programmer after all).
