Ancient fun-fact: Years ago there was an article in Byte magazine 
describing how a useful subset of C could be directly assembled into 68000 
code. Not compiled, assembled.

C is a stunning assembly language. When those wild-eyed nerds at AT&T 
decided to write Unix not in assembly but in C (where was management!?), 
it was radical. But C was up to (down to?) the task, it was pioneering 
then and is still doing useful things decades later: From the fastest 
supercomputers to some pretty slim microcontrollers (plus a hell of a lot 
of Android devices) multitudes of computers run a Linux kernel compiled 
from the *same* C source code, with almost no assembly. Big-endian, 
little-endian: no matter. Different word lengths: no matter.

That is one impressive cross-platform assembly language!

Unfortunately, C is also a dangerous language that mortal programmers 
cannot reliably wield.

-kb, the Kent who knows he is pressing his luck on a moderated 
cryptography mailing list, but C deserves a lot of respect, as it also 
deserves to be efficiently sent into a dignified retirement.
