digitalmars.D.learn - what's the point of function template declarations if they can't be

```
void fun_bad3(T)(T a);  // declaration [1]

void test(){
  fun_bad3(1);
}
```
Error: test_all.fun_bad3 called with argument types (int) matches both:
main.d(11):     test_all.fun_bad3!int.fun_bad3(int a)
and:
main.d(12):     test_all.fun_bad3!int.fun_bad3(int a)

should [1] be allowed? compler doens't allow defining it afterwards in
[2] (unlike function definitions, and, well, modulo this regression

Perhaps if it's defined in another file. -- /Jacob Carlborg
