Hello all,
I have an older system I am trying to build dmd-2.102.2 on from source:
stock Slackware 14.0 x86_64
binutils 2.22.52.0.2, gcc 4.7.1, glibc 2.15, kernel 3.2.x, and
dmd-2.102.1 installed (which I built from source on this system)
I started with dmd-2.067.1, bootstrapped it with only a

Hello,
I created a short guide on getting started with D:

This is because I recently I started to explore the language and, having

Wanted to try out linking two source files independantly compiled.

If not calling C code, why use extern(C) for D code?
Wanted to test out options of calling D routine (possibly -betterC) from
both C and (full) D.
OK, thanks.
This is a followup to my original post on March 9 about issues building
dmd-2.102.2 on an old Linux x86_64 system.
See bugzilla:
https://issues.dlang.org/show_bug.cgi?id=23846
The short answer is it is fixed as of dmd-2.104.0-beta.1, that version
now builds dmd and phobos successfully.

TLDR: `r"^."` is matching the very first two character in the `input`
string.
Don't you need two dots to match two characters?
Each dot being the regex to match a single characte

The following code:
ulong charlie = 11;
long johnstone = std.algorithm.comparison.max(0, -charlie);
writeln(format!"johnstone %s"(johnstone));
Results in (without any warning(s)):
johnstone -11
However you choose to look at it, this means -11

Well, I don't think that auto is a particularly controversial topic among D

Thank you Jonathan for that very detailed response.
This thread can end now unless others really feel the need to comment.

In idiomatic D, you'd use `auto` when either (1) you don't care what the
type is, you just want whatever value you get to be shoved into a
variable, or (2) you *shouldn't* care what the type is, because your
code shouldn't be depending on it, e.g., when y

I tried it and it seemed to work OK.
Wondering if there are any good reasons to use auto,
or bad reasons why not to use auto here?

I am one of those where code snippets are not an effective way to learn.
