problem with placing qualifiers in front is that it looks
s were placed after the function parameter list
(int i). Just for fun, I moved to type qualifiers before the
function definitions "this" (like a return type?) and the output
was exactly identical. So I guess my question is, is this just
a matter of esthetics or is some more nuanced goal at work here?

It should be here: https://dlang.org/spec/abi.html although

If I declare a function as extern(C) inside a DLL, I have also to
cast the function pointer as extern(C) or it fails calling, eg.
```d
// --- my.dll
export extern (C) void log(int mode, string a, string b, string
c) {
/* stuff */
}
// --- main.d
alias T = extern (C) void function(int,

Isn't this normally a compiler's job to eliminate

Somebody else mentioned this before but none of the programs we've seen
so far seemed to need a special random
same as above line?
//writeln(howManyTimes.iota.map!(5 => rnd.dice(0.6,
1.4)).format!"%(%s,%)");
}
// ---
No, it's not the same. 'Tis not really a "map question", looks
more like a question about
https://dlang.org/spec/expression.html#function_literals (see
#10).
trying to make sense of the below:
// ---
module test;
import std;
void main()
{
auto rnd = Random(unpredictableSeed);
int howManyTimes = 5;
// ok - using 'e =>' makes sense
writeln(howManyTimes.iota.map!(e => rnd.dice(0.6,
1.4)).format!"%(%s,%)");
// ok - though

The following should do it:
debug {} else {
foo();
}

`debug` is like a `version` block.
```d
debug {} else {
