pure, nothrow, @safe, and @nogc are infered for templated functions. So,
whether those attributes apply when they're not explicitly marked on a
templated function deponds on the contents of the function. You can test it
with a unit test. e.g.
@nogc unittest
{
...
foo.func();
}
will give a compiler error if func wasn't infered as @nogc.
