I don’t remember Boo syntax, but in Nemerle you can just write

[Accessor(flags = WantSetter)]
mutable _someField : int;

and it will be converted at compile time to

mutable _someField : int;
public SomeField : int {
get { some_field }
set { some_field = value }
}

Writing a macro which would insert FirePropertyChange calls as well is pretty easy.

[NotifiableProperty]
public string _firstName;

and it will be converted to

public string FirstName
{
get { return _firstName; }
set
{
if (_firstName != value)
{
_firstName = value;
FirePropertyChanged(”FirstName”);
}
}
}

at compile time, no run time overhead! See here: http://nemerle.org/Macros

int age;
Switch.On(”Paul”)
.Case(x => x == “George”, () => { age = 40; })
.Default( () => { age = 70; })
.Case(x => x == “Paul”, () => { age = 25; });

In this situation age would be set to 70 instead of 25.

I think the Default() method signature will have to be updated to return void instead of Switch. This will ensure that Default() is always at the end of the statement and is only called if none of the Cases have been met.
