>Description:
g++ failes to accept (T()) as an argument of a function 
(or operator, such as sizeof) that expects a T:

t.cpp: In function `int main ()':
t.cpp:2: parse error before `)'
>How-To-Repeat:
int main(){
  (void) sizeof( ( int() ) );
}
>Fix:
Trivial for the above code, but I need the mechanism to work
in templated code without a T actually being created. I know
of no workaround for this.
