Followups have been redirected here!!  I don't read alt.flame.

And you do, I suppose?  Then you can explain why you think C is
faster than other languages in spite of the fact that it is inherently
harder to optimize.  Once a program has been parsed and is represented
by an abstract syntax tree (or some other intermediate representation)
it is nearly impossible to tell what language the original source was
in - except C which has more aliasing and potential dependencies than
most other languages.  Also, C's character processing is less efficient
as well.  In those respects that are important to compiling, C is
nearly identical to most other imperative languages.  In those respects
where it differs, it is harder to optimize.

Is that the peculiar mental condition which prevents you from discussing
