Hello! I'm new in D and it is amazing!
Can you tell me please if it is discouraged or deprecated to
call a function by just putting its name, without brackets?
It's quite unusual for me (used C++ and Python before), but I
can see this practice even in the official Phobos documentation:
```
foreach (result; [ 1, 2, 3, 4 ].map!("a + a", "a * a"))
...
```
The code `.map!("a + a", "a * a")()` also compiles and works as
expected, of course.
