Representational Method Signature

[BigSquareHasNoEdge]

How about this idea?
Wouldn't it be interesting if C# compiler would have this feature?

Declaration type 1:
void On(string propertyName)PropertyChanged { }

call:
On("Name")PropertyChanged;
or
On%PropertyChanged("Name");
or
OnPropertyChanged("Name");

Declaration type 2:
void Add(int n)To(Store store){ }

call:
Add(1)To(myStore);
or
Add%To(1, myStore);
or
AddTo(1, myStore);

Declaration type 3
void Subscribe(object subscriber)To(string messageKey)Of<TPublisher> { }

call:
Subscribe(this)To("ProductAdded")Of<ProductViewModel>;
or
Subscribe%To(this, "ProductAdded")Of<ProductViewModel>;
or
Subscribe%To%Of<ProductViewModel>(this, "ProductAdded");
or
SubscribeToOf<ProductViewModel>(this, "ProductAdded");

This style is one of the things I dislike about Objective C...

This can be even harder to understand for non-English speakers.
