How do I apply just the template arguments to a function that expects template arguments, without implicitly also calling the function with zero arguments? I want a function or delegate pointer instead of a value.
void foo(T)(double x) {}
auto bar() {
return foo!(int);
}
hack.d(36): Error: function hack.foo!int.foo(double x) is not callable using argument types ()
hack.d(36): missing argument for parameter #1: double x
If you had an ordinary function
void foo() {}
and you wanted a function pointer to it, how would you do that?
&foo
Now, suppose you have a template:
void foo(T)() {}
and want a pointer to a specific instance... you can probably guess at this point :)
&foo!arg
