Since you watch Star Trek, I'd suspect you watched Red Dwarf too.  :)
Didn't you?  Admit it.  Red Dwarf had "smeg."  And, your British TV
shows use "bloody" - basically like the F-word here - without
censoring it.  You don't find "bloody" offensive, do you?

Well, I'm surprised.  It's not used in an expletive context.  "Innit?"
So, why "omit further reference to that language," if it's just the
use of the expletive which offends you and not the language?  ...
Some use "BF" instead for just that reason.

Besides,I thought we had discussed that programming language more than
a few times in the past without any objection by you to either the name
or the actual language.  Perhaps, this was on c.l.m?  It's novel in it's
simplicity.  It seems you hate the language now too ...

Personally, I'm opposed to all censorship.  I prefer to be respectful
to the actual name of the programming language.

An abstract syntax tree is constructed.  It's just that a set of grammar
rules wasn't used to construct it.  I.e., the ordering of language
elements, or recursive nature as you call it, isn't information which
is being checked for by logic and/or being recorded in the tree, stack,
etc.  Hence, pairing/matching issues of while with do or not, etc.

I will attempt to get back your three other posts later.
Currently, I can't stop laughing at one mine in the Smaller C
thread ... :-)  I will have wait to see how you responded, i.e.,
if you took it jokingly or angrily or seriously.
