Hmm, didn't think of it. I phrased it differently now.
In my experience, the participants' nicknames in competitive
programming are mostly tightly coupled with real names, and
otherwise, the blog author's profile is one familiar click away.
So for a local Codeforces reader, that hopefully wasn't a problem
anyway.
2. When you briefly explain templates I think it's important to
mention that empty parentheses may be omitted to allow the
reader to make the link between function!(arg1)(arg2) and
map!something. Explaining UFCS isn't necessary there though I
think since it's obvious that there is some kind of chaining at
play (not that you did, just thinking out loud).
Yeah, good point, mentioned it now.
Also I have a question: I find very nice that some platforms
propose D even though not all do, but are they generally
keeping it up to date with DMD or stuck at something ancient?
It varies depending on the platform. A few examples:
codeforces.com just recently upgraded from DMD 2.074 to DMD 2.079
(so I could show the compile-time writefln in the post);
atcoder.jp is at DMD 2.070 but also has LDC 0.17.0 and GDC 4.9.4;
codechef.com has some ancient GDC, barely usable;
hackerearth.com has DMD 2.074.1;
csacademy.com (Romanian competitive programming website) does not
yet have D, but I hope they add it in a few months;
hackerrank.com claims to have DMD 2.079, but recently stopped
supporting it in live contests because of a paradigm shift.
Namely, they now strive to supply the reading-from-file solution
template for each problem, and apparently didn't get to writing
it in all 35 languages they generally have. I offered my help,
but the support was kind of unresponsive, so seeking another
point of contact now.
Generally, it seems to correlate with the health of the
platform's backend.
In my code in competitions, I tend to now use features around
2.070 so that they are mostly supported.
