------------------ Additional Follow-up Comments ----------------------------
csc also gets confused, thinking that the construct is a
cast instead of an invocation.  It even complains that "cb"
is not declared because it is trying to locate it as a
type.  I'm surprised that SDL.NET compiles at all if
it is using code like this.  More information required
before I can go further with this.

found (are you missing a using directive or an assembly reference?)
ambiguity.cs(8,18): error CS0201: Only assignment, call, increment, decrement, 
and new object expressions can be used as a statement

Summary:  C# Compiler:: Ambigous typecast vs delegate in brackets

Original Submission:  The compiler fails to realize

(cb)(null);

is the call of the delegate cb with args null.

and one case throws a parser error as well ?.

(From SDL.net code ...)
