Say I have declared a class with something like this:

public class Postler.Messages : Gtk.TreeView {
    public string? selected_location { get; set; }

So I can connect to changes of the property like this:

messages.notify["selected-location"].connect ((object, pspec) => {

The problem is, there is no compile-time error if I fail to type the property name. It will not give a runtime error either. Nothing will happen at all. And then I start wondering why my lambda isn't working.



I would expect a runtime error if the property doesn't exist.

I would want a non-string syntax, such as

messages.notify.selected_location.connect

which is what I tried but apparently doesn't work. Or alternatively

messages.selected_location.connect

which would also make sense to me. But Vala says "string has no such method".
