Well, I'm still confused by this. I also noticed that the compiler
doesn't complain if I omit the break statements in the generated
switch, but complains normally if I write it out like so:
```
switch (key)
{
case 1: "Found 1!".writefln();
break;
case 2: "Fo

it, but that way it would just be a pointer.

Thanks everyone for figuring everything out!
It also throws if you input initial or trailing spaces and there
are no spaces at the start or end of format string (scanf skips
these spaces)

Just like in scanf, a single space character is sufficient to consume
zero or more whitespace characters.

This is true when using the D format functions (e.g. readf) which are
able to inspect the types of the variables being assigned, but scanf is a
C function and not types
Thank you everybody!!!
I thought %d is ok for all integral types.

After scanf in loop variable n becomes 0. Is this a bug? Please
help me!
Have you tried to use a tmp of type int to avoid stomping?

ref doesn't work with anything other than function arguments in D.

The following:
this(ref InputRange r) {
writeln(&r);
this.r = r;
writeln(&this.r);
}
7FFF2BD74D50 // r
7FFF2BD745F0 // this.r
Why? And how can I change this?
Why does the read function return void[] and not byte[]
void[] read(in char[] name, size_t upTo = size_t.max);
