----------------
I am trying to be a bit more helpful here although I am not sure if we should
instead require explicit template parameter and fail the template deduction
instead.
Basically, do we want the following code to always require specifying template
argument explicitly:
```
template <class T>
T xxx(T *in) {
T *i = in;
return *i;
}
__kernel void test() {
int foo[10];
xxx<int>(&foo[0]); // if we deduce type from foo, it ends up being qualified
by __private that we currently diagnose. However private is default (implicit)
address space for return type so technically there is no danger in just
allowing xxx(&foo[0])
}
```
