Wait, which proposal? To replace && and || with 'and' and 'or'?

Or my slightly extreme rant about replacing '==' with '=' and '=' with
':=', amongst other things?

Well, it's hard to explain. Proposals like python's semantic 
whitespace or golang's "array of ints should be typed as []int in 
order to match the pronunciation sequence: array-of-ints" or 
equality should be '='. I don't know why, but they have something 
in common.

These come from Python users. :P

And maybe the fact that some people, for reasons unknown to me, just
can't stand the sight of delimiting blocks with '{' and '}'. It's almost
as if they get the creepy-crawlies when they see '{' and '}'. They'd
much rather deal with words like 'begin' and 'end', or Python's semantic
whitespace.

That's just a native language bias. Well, it's not even that. If you
interpret 'int' as an adjective, then int[] totally makes sense. But if
you interpret 'int' as a genitive noun, then it'd be []int.

To me, I find []int ineffably ugly. Even array(int) is better than
[]int. But that's just me. Whether you write

	int x[];

or

	int[] x;

or

	[]int x;

or even

	x int[];

or any other permutation thereof, ultimately it's just a matter of
conveying three pieces of information to the compiler: the name of the
variable, the base type, and the fact that it's an array of the base
type. If you could write code in 3D, you could equally well put these
three elements in a triangle parallel to the flow of code, in which case
order wouldn't even be an issue.

So it all boils down to personal preference.

That's coming from math geeks like me. :P

I'm not sure I know what you're referring to. What else do they have in
common, besides wanting to tweak language syntax to suit one's own
preferences?

Preferences are shaped by what one is familiar with.  I'm sure if you
manage to herd enough APL programmers in here, they'd be clamoring for D
to start using APL symbols instead of this verbose procedural trash like
for-loops. :-)

Or if you herd enough Lisp programmers in here... oh wait, we already
have std.functional. :-P  The only thing missing is to replace all ;
with , (except after the last statement in a block), standardize on ()
for {}, [] and (), then rename some keywords, and it'd be Lisp heaven on
earth!

So let's make '+' be '$' and '-' be '+'? My point wasn't that 
mathematical equations are identical to sequential code 
statements, but that they should, as much as possible, attempt to 
stay inline. It's all about how difficult programming is to 
pick-up.

Sounds like an esolang (http://esolangs.org/wiki/Main_Page) :)

Maybe I should invent one. I'll call it EsoD, for Esoteric D (or Evil
Strain Of D). Syntax is exactly the same as D, except that instead of
(), [], and {}, we write ~!, @#, and $%, respectively, and all keywords
are spelt backwards. Addition is denoted ^, multiplication &,
subtraction *, and division (. Assignment is denoted ), equality is -,
and field access {. Lists are delimited by +, and statements end with =.
Since } isn't used for anything, we'll use that instead of @ for
properties.

So for example, here's a function that computes the average of an array:

	}efas erup tsnoc a f~a+z!~ni z@# b! $
		a c)0=
		hcaerof~d=b! $c^)d=%
		nruter c(b{htgnel=
	%

Here's an example of how to use it:

	tropmi dts{oidts=
	diov naim~! $
		nletirw~f|~laer!~@1+2+3+4+5#!!=
	%

If this looks hard, don't worry, once you are past the initial learning
curve, it will all become crystal clear to you. ;-)

Could be promising for dyslexics ;)

The problem I had with it was having to stop myself from reading the
entire lines from right-to-left.
