  C (K&R) : 1972 => 53 years ago
  C++     : 1985 => 40 years ago
  D       : 2001 => 23 years ago

So D is 30 years younger than C, so I'd disagree with "isn't that much younger".

D was really a reaction to C++, not C, so it is with C++ that it should be compared. The C like subset of D (BetterC) is much more recent.

I was thinking more about Ansi C. But fair enough. I hope the core point that these are all still Languages old enough to drink rings through.

Except ANSI did very little in terms of changing/enhancing the language. It stayed largely as it had been since Nov '78:

Nov 78 Memo: https://www.bell-labs.com/usr/dmr/www/cchanges.pdf

About all that happened with ANSI C was that prototypes were created (the major addition), type promotion rules were altered, plus 'const' and 'volatile' were added. ANSI also added 'void *'.

I've a vague recall about 'void' existing in unix C compilers before that, having read a version of the above memo in a unix manual ('papers' section) and it mentioning 'void'.
