The idea isn't stupid but I think it is already handled. For
template<int N> void f() {}
template<int N = 1000000 * 10240> void g() {}
void foo() {
f<1000000 * 10240>();
g();
}
I got errors
template-args.cpp:2:18: error: non-type template argument is not a constant
expression
template<int N = 1000000 * 10240> void g() {}
^~~~~~~~~~~~~~~
template-args.cpp:2:26: note: value 10240000000 is outside the range of
representable values of type 'int'

3 errors generated.
Do you have some other template arguments usage in mind?
