How to get rid of "nothrow" ?

[Vinod K Chandran via Digitalmars-d-learn]

Hi all,
I am trying to create a win32 based gui in dlang. So far so good. 
I can create and display my window on screen. But for handling 
messages, i planned to write something like message crackers in 
c++. But since, my WndProc function is a "nothrow" function, i 
cannot use any function without "nothorw" in that WndProc. How to 
solve this problem ?
