Templatized operator () overload

[Paul Escherton]

I'm trying to templatize the operator(), but VisualStudio .NET 2003 I
get an odd error. I'm wondering if there is a way to do this and what
the proper syntax is. If there is not, why not?

My code looks like:

class DaClass
{
public:
template <class T> T operator( ) ( )
{
return T;
}
};

and I attempt to call the operator like this:
DaClass daClass;
daClass<bool>( );
daClass<bool>operator( );

I get an error on both the lines where I try to call the operator of:
'type 'bool' unexpected'.

Any thoughts? Thanks in advance.

Your trying to return a type? ("return T;") Can't do dat! You need to
return a value of the type!

The above syntax is wrong. How about:

daClass.operator()<bool>();

But why do you want to template operator() it only on the return type?
I can't think of any use for that, since you can't call the function
without explicit template parameters.
