Hello,
just another one try to use a property in an interface.
1. It's so unnatural that an implementation of a property must match
exactly to its declaration. Though it should be a superset of the
declaration (as in C#):
valac cl1.vala if1.vala
cl1.vala:3.3-3.20: error: Type and/or accessors of overriding property
`NS1.Cl1.str1' do not match overridden property `NS1.I1.str1'
2. Because of the point 1, one have to write such strange things as:
public string str1 { get; private set; }
Though it doesn't work either (i.e. valac cl1.vala if2.vala ). I hope
that the patch of Alexander Bokovoy will fix that (see that letter):
Subject: Re: [Vala] interface properties: unexistent accessor

====================
What do you think about changing this in Vala - to how it woks in C#:
1. Implementation is a superset of the declaration in interface.
2. Prohibit private accessors in interfaces.
I attach a small example.
Best regards, Ildar
