Question on @nothrow

[Vasileios Anagnostopoulos via Digitalmars-d-learn]

Hi,

after reading various articles bout the "supposed" drawbacks of 
checked exceptions I started to have questions on @nothrow. Why 
there exists and not a @throws annotation enforced by the 
compiler? I understand that people are divided on checked 
exceptions and each side has some valid points. But explicitly 
marking a function as throwing "something" is another subject. 
Why have the dlang community reached to the decision to use 
@nothrow and not a @throws?
